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.

Here time is constant = t;

No old speed = 10 new speed 10*14/10.

D-14/10d = 20.

D = 20*10/4 = 50 km.

14 - 10 = 4,
20/4 = 5,
5 * 10 = 50.

Please solve this.

While covering a distance of 60 km, A takes 4 hours more than B. If A doubles its speed, A took 2 hours less than B. Find the walking speed using a simultaneous equation or quadratic equation.

Given;

14kmph at 20 km MORE i.e extra speed.
So we can write it as 4 kmph -20.,
Each km 20÷4 = 5.
Hence 10 * 5 = 50.

Let actual distance x km.
Actual speed =10 kmph T1 = ?

Man walk 20 km more,
Distance = x + 20.
Speed = 14 kmph T2 = ?

Now T1 = T2.
D1/S1 = D2/S2.
x/10 = x + 20/14 after solving x (actual distance) = 50 km answer.

@Gowtham, @Ilesh.

Both are explained very well. Thank you.
