Answer: Speed of Rakesh is Better than that of Behram.
Step-by-step explanation:
Step1) Total distance Rakesh cycles= 18 km
Time Taken by Rakesh to cover 18 km= 3 hours
Speed of Rakesh= 18/3
= 6 km/hour
Step2)Total distance Behram cycles= 20km
Time Taken by Behram to cover 20 km= 4 hours
Speed of Behram= 20/4
= 5 km/hour
Step3) Speed of Rakesh= 6 km/hour
Time Taken by Rakesh to cover 60 km= 60/6
= 10 hours
Time Taken by Behram to cover 60 km= 60/5
= 12 hours

hi,
here is the solution--
~~~~~~~~~~~~~~~~~
speed of Rakesh :--
= distance/time
= 18/3
= 6 km/h
speed of behram :--
= d/s
= 20/4
= 5km/h
Rakesh will take time to cover 60 km :--
==>time = distance/speed
==> time = 60/6
==> 10 hours
behram will take time to cover 60 km :--
==>time = distance/speed
==>time = 60/5
==> 12 hours
the performance of Rakesh is better then behram because his speed 6 km/ hours.
and he covers the distance in 10 hours
