Question

Mr Sam takes 3 hours more than Mr Jain to walk 60 km but if Mr Sam double his pace he is a head of Mr Jain by one and half hours find the speed of walking

Answer 1

Dear Student,

◆ Answer -

Speed of walking of Mr Sam = 6.667 km/hr

● Explanation -

Let x and y be speed of Mr Sam and Mr Jain respectively.

60/x = 3 + 60/y ...(1)

After doublimg speed,

60/2x = 60/y - 1.5 ...(2)

Substracting (2) from (1),

60/x - 60/2x = 3 + 60/y - 60/y + 1.5

60/2x = 4.5

x = 30/4.5

x = 6.667 km/hr

Hence, the speed of walking of Mr Sam is 6.667 km/hr.

Thanks dear. Hope this helps you...
