Question

A bus takes 30 min to cover a distance of 18 km. Calculate its speed in Km/hr and m/sec​

Answer 1

Answer:

36km/hr, 10m/s

Step-by-step explanation:

we know that

speed= distance / time

so speed = 18km/ 30min = 18km /0.5hr = 36 km/hr

1km =1000m and 1hr = 60 ×60 sec

36km /hr = 36×10^3 m/ 60 ×60sec = 10m/s

Answer 2

30 mins to cover 18km
I) km/h= 18/0.5
= 36 km/h
II) m/sec= 18000/1800
=10m/sec
