Question

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

Answer 1

Answer:

Step-by-step explanation:

Distance=18km=18*1000 m= 18000 m

time=30min=30/60 hr= 1/2 hr=30*60 sec= 1800sec

Speed(in km/hr)=D(in km)/t(in hr)=18/(1/2)=18*2 km/hr= 36 km/hr

Speed(in m/s)=D(in m)/t(in sec)=18000/1800=10 m/s
