Question

A passenger train, running at a speed of 80 km/hr
leaves a railway station 6 hours after a goods train
leaves and overtakes it in 4 hours. What is the
speed of the goods train ?​

Answer 1

Answer:

speed |time

• 80 | 6

x | 4

• 6x =80 × 4
• x = 80 ×4

-----

6

• = 48

Answer 2

Let the speed of goods train be x km/h.

∴ Distance travelled by goods train in 10 h = distance covered by passenger train in 4 hours

⇒ 10x  =  80 × 4

x = 320/10

x  =  32 km/h
