Question

a bus travel 30 minutes to cover a distance of 18 kilometre calculate the speedin kilometre per hour and metre per second

Answer 1

Explanation:

Speed = distance/ time

in m/s

1km = 1000m

so, 18km= 18000

30min= 30× 60= 1800sec

speed= 18000/1800

speed= 10m/s

in km/hr

30min = 1/2 hr

speed = 18÷(1/2)

speed= 36km/hr
