Question

A scooter travels at a speed of 30km/h to cover a certain distance in 4 hours. what should be his speed if he has to travel the same distance in 3 hour​

Answer 1

Answer:

The scooter must travel at a speed of 40 km/h to reach in 3 hrs.

Step-by-step explanation:

We know that,

Speed = Distance/Time

So,

Distance = Speed × Time

We are Given,

Speed = 30 km/h

Time = 4 hrs.

Then,

Distance = 30 × 4

Distance = 120 km

Now,

We must reach in 3 hrs. instead of 4hrs.

So,

Speed = Distance/Time

Speed = 120/3

Speed = 40 km/h

Hence,

The scooter must travel at a speed of 40 km/h to reach in 3 hrs.
