Question

two trains traveling along parallel tracks in the same direction do 50 km per hour and one hundred km per hour on average the fastest train starts 2 hours later than the slower after how many kilometers will the fastest train catch up?

Answer 1

Answer:

the faster train would catch up after 200 km.

Step-by-step explanation:

Since we have given that

Speed of two trains travelling in the same direction = 50 km/hr, and 100 km/hr

According to question, the faster train starts 2 hour later than the slower.

Let the time taken by faster train be 't'.

Let the time taken by slower train be 't+2'

So, the equation when they meet.

50(t+2) = 100t

50t + 100 = 100t

100 = 100t - 50t

100 = 50t

t = 100/50

t = 2 hrs

So, the faster train would catch up after

100 x 2 = 200km

Hence, the faster train would catch up after 200 km.
