Question

A train covers certain distances in two parts. Distance covered in first part is 200% more than the distance covered in second part while speed of train is in the ratio 2:1 in first and second part respectively. If average speed of train is 64 km/hr, then find the speed of train in first part in kmph

Answer 1

Answer:

96

Step-by-step explanation:

speed ratio = 2:1

let speed while covered 1st part be 2x

and during 2nd part it be 'x'

average speed = 64km/hr

2×2x×x/(2x + x) = 64

x = 48km/hr

So 2x = 2×48 = 96km/hr

speed of train in 1st part = 96km/hr
