Aptitude - Time and Distance - Discussion

Discussion Forum : Time and Distance - General Questions (Q.No. 3)
3.
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:
50 km
56 km
70 km
80 km
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.

First calculate as:

Time = Distance/Speed = 20 km/14-10 kmph = 20/4 = 5 hr.

Means time = 5 hr.

Distance = Time*Actual speed.

Distance = 5*10 = 50 km.

Here time is constant.

S, the o formula for time is Distance /Speed.
10/x = 14/x+200.
Equate this we will find:
10x + 200 = 14x,
4x = 200,
X = 50.

Why t in both the equation is same?

If a person is walking at 14km/hr then it will take less time then 10km/hr, which means both t are different.

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.

The difference per hour is 14 - 10 = 4 km.
So, the time taken to travel 20 km is = 20/4 = 5 hours.
Now, the actual distance = 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.

Here in this question both the times are equal. So we use s1/d1 = s2/d2.

Therefore: 10/x = 14/x+20.

10x+200 = 14x.

4x = 200.

x = 50.

The actual distance 50km(10km) but he travelled 70km by 14kmph, the question is THE ACTUAL DISTANCE TRAVELLED BY HIM? Is it 70 or 50?

Parikshit said:   8 years ago
If 10kmph will cover x distance than 14 will cover it faster. But why here 20 km is added to 14kmph distance. How can it be possible?

Distance= (a/x-y) * y.
a=20km
X=14 KMPH.
Y=10 KMPH.
(20KM/14KMPH-10KMPH) * 10KMPH.
(20KM/4KMPH) * 10KMPH.
So, the answer is 50KM.
