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.

Here time is constant = t;
No old speed = 10 new speed 10*14/10.
D-14/10d = 20.
D = 20*10/4 = 50 km.
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.
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.
