Question

a car travels at 40 kilometre per hour how far does it travel in 7 minutes​

Answer 1

First convert 40km/h into m/s

That is,

$\frac{40}{3600} \times 1000$

We get

11.11m/s

Now,

If the car travels 11.11 meters in second, then how many meters in 7 minutes?

7 minutes = 7 × 60 seconds = 420 seconds.

So,

The distance travelled in 420 seconds (7min) :

420 × 11.11

4666.66..meters

OR

4.666..Kilo meters
