Question

Rakesh cycles 18 km in 3 hours and behram cycles 20 km in 4 hours who has the better speed? How long will each take to cover a distance of 60 km

Answer 1

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

Answer 2

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
