Question

calculate the time(in hour)taken by a bus travlling at a speed of 10m/s to travel a distance of 72km​

Answer 1

Explanation:

Speed=10m/s

Distance=72km/h=72*5/18

=20m/s

Time=distance/speed

=20/10

2sec

Answer 2

Answer:

$\large{S=d/t}$

speed=10m/s

distance=72km=72000m

time(in hour)

$\large{10m/s=72000m/time}$

$\large{time=72000m/10m/s}$

$\large{time=7200s=7200/3600h}$

$\large{Time=2hour}$
