Question

A distance of 800 metre is covered in 30 minutes find the speed in kilometre per hours

Answer 1

30 minutes = 30/60 = 0.5 hrs
800 meters = 800/1000 = 0.8 kilo meters
Speed = Distance / Time
           = 0.8/0.5
           = 8/5 ( Multiply numerator and denominator by 10 )
           = 1.6 km/hr
 Therefore, the speed is 1.6 km/hr
 

Answer 2

The speed will be 1.6km/hr.
