Question

A bus travels 54 km in 90 minutes. The speed of the bus is in metre second



​

Answer 1

Explanation:

Speed = distance / time = 54 km / (3/2) hr = 54*2 / 3 = 18*2 = 36kmph . A bus travels 54 km in 90 minutes. the speed of the bus is 36 kmph

Answer 2

Explanation:

54 km = 54*1000 = 54000 metre.

90 min = 90*60 = 5400 seconds

$\frac{54000}{5400}$

= 10 metre per second
