If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:
Answer: Option
Explanation:
Let the actual distance travelled be x km.
| Then, | x | = | x + 20 |
| 10 | 14 |
14x = 10x + 200
4x = 200
x = 50 km.

According to me, by using the simple formula we can iterate lucidly like this way,
Let the time be x hours
According to the question;
14x - 10x = 20
4x = 20
x = 5 hours.
His actual speed is 10 km/h.
So, the actual distance is 10 * 5 = 50 km.
Let the time be x hours
According to the question;
14x - 10x = 20
4x = 20
x = 5 hours.
His actual speed is 10 km/h.
So, the actual distance is 10 * 5 = 50 km.

Given:
S1= 14km/h
S2= 10km/h
D1= 20km
D2=?
Solution:
We know that; (Distance= Speed * Time)
We first need to know the time taken,
By putting values:
20km = 14km/h (s1) - 10km/h (s2)
20km = 4 km/h,
20/4 = 5.
So the time (T) is 5.
Similarly, putting values we get;
D2 (actual distance)= 10km/h (actual speed) * 5 (time).
Distance= 10*5km.
Actual distance= 50km.
S1= 14km/h
S2= 10km/h
D1= 20km
D2=?
Solution:
We know that; (Distance= Speed * Time)
We first need to know the time taken,
By putting values:
20km = 14km/h (s1) - 10km/h (s2)
20km = 4 km/h,
20/4 = 5.
So the time (T) is 5.
Similarly, putting values we get;
D2 (actual distance)= 10km/h (actual speed) * 5 (time).
Distance= 10*5km.
Actual distance= 50km.

Very easy approach:
Here d1 - d2 = 14 - 10 = 4km/h.
Now 4 = 20.
Then 1 = 5.
The actual distance is 10 * 5 = 50km.
Here d1 - d2 = 14 - 10 = 4km/h.
Now 4 = 20.
Then 1 = 5.
The actual distance is 10 * 5 = 50km.

By ratio method, if time is constant speed is directly proportional to distance so;
speed: 10 : 14.
distance : 10x : 14x.
difference btw (10x-14x) = 4x.
4x = 20,
x = 5.
Put this in the usual speed 10x= 10*5=50 km.
speed: 10 : 14.
distance : 10x : 14x.
difference btw (10x-14x) = 4x.
4x = 20,
x = 5.
Put this in the usual speed 10x= 10*5=50 km.

His actual speed is 10 km/h and from given question.
14x-10x = 20,
4x = 20,
x = 5 hours.
then the actual distance will be;
10*5 = 50 km.
14x-10x = 20,
4x = 20,
x = 5 hours.
then the actual distance will be;
10*5 = 50 km.

The speed of man is =10km/hr.
In question that given if he walked 14km/hr instead of 10km/hr,he will reach
20km more(but the time is same).
If he walked 10km/hr, we take that distance covered is Xkm.
If he walked 14km/hr, we take that distance covered X+20km.
But for a both cases time is the same.
(Time = distance/speed).
Since X/10 = (X+20)/14.
14X = 10X+200
4X = 200
X = 50km.

According to me;
Here d1-d2 = 14km/h-10km/h=4km/h
Now 4 unit = 20.
Then 1 unit = 5.
Then the actual distance is 10*5 = 50km.
Here d1-d2 = 14km/h-10km/h=4km/h
Now 4 unit = 20.
Then 1 unit = 5.
Then the actual distance is 10*5 = 50km.

The difference between distances is 20km and d = s * t.
So 14x-10x = 20.
x = 5hrs
The actual distance is s*t = 10 * 5 = 50km.
So 14x-10x = 20.
x = 5hrs
The actual distance is s*t = 10 * 5 = 50km.

His actual speed is 10 km/h and from the given question.
14x-10x = 20,
4x = 20,
x = 5 hours.
Then the actual distance will be;
10 * 5 = 50 km.
14x-10x = 20,
4x = 20,
x = 5 hours.
Then the actual distance will be;
10 * 5 = 50 km.

At usual time Period, a man Covers a Distance of 10 KM/hr ,But he has increased the Speed to 14 km/hr.
That means he will going 4 Km/hr additionally.
To Cover the Distance of 20 km with the Same of 14 km/hr he has to travel additional 5 hours.
4km * 5hrs = 20 km.
After 5 hours of travel if the person is travelling at the speed of 10 km/hr covers;
D = S * T/
D = 1 0 *5.
D = 50 KM.
That means he will going 4 Km/hr additionally.
To Cover the Distance of 20 km with the Same of 14 km/hr he has to travel additional 5 hours.
4km * 5hrs = 20 km.
After 5 hours of travel if the person is travelling at the speed of 10 km/hr covers;
D = S * T/
D = 1 0 *5.
D = 50 KM.
