Question

A passenger train having speed of 80 km/h
runs from a station 6 hours after a goods
train has started from that station and
crossed the goods train after 4 hours. What
is the speed of goods train?
(A) 32 km/h (B) 48 km/h
(C) 60 km/h (D) 50 km/h
​

Answer 1

Answer:

Step-by-step explanation:

Let the goods train speed be x.

Distance between the tràin and the stàtion = v×t

= 80×6 = 480 km

Now,

According to question,

both tràin pàss each other in 4 hours,

Mòving tòwards each other, their spèeds will be added.

(x+80)×4 =480

-> x+80 = 120 Km/hr

-> x = 40 km/hr
