Two trains 15

A train travelling at 50 km/h leaves Delhi at 8 AM and another train travelling at 70 km/h leaves Delhi at 11 AM in the same direction. How many km from Delhi will they be when the faster train catches the slower one?

Final Answer:

s =  525 km

Step-by-step explanation:

v1=50 km/h v2=70 km/h  Δt=118=3 h  s=s1=s2  v1 (t+Δt)=v2 t 50 (t+3)=70 t  20t=150  t=20150=7.5  t=215=7.5  s=v2 t=70 7.5=525 km
