Question

a bus moving with a speed of 20m/s calculate the distance travelled in 4 hours
(Plz tell me fast my mock test is going) ​

Answer 1

Answer:

The distance covered by the bus in 25 minutes is 30 km

Step-by-step explanation:

Given: speed = 20 m/s ; time = 25 minutes

Question ; distance = ? in km

First step: Convert 20 m/s to km/h

Second step: Convert 25 minutes to hours

In the first step, To convert 20 m/s to km/h we would multiplly 20 m/s by 3600/3600.

We get (20 * 3600) m / (1s*3600) = 72000 m/3600s = 72 km/h

Knowing the speed in km/h we multiply it by 25 minutes/60 minutes and we get 5/12 h.

So 72 km/h * 5/12 h = 30 km after cancellation

The distance covered by the bus in 25 minutes is 30 km

Answer 2

Answer:

speed

Step-by-step explanation:

we know that

speed =distance/time

distance=speed *time

20 m/s*4

=100m/s
