Question

Motion problem

Answer 1

Answer:

4.5 hours

Step-by-step explanation:

Given: Train running in opposite direction

           Speed of one train ($S_1$)= 35 mph

           Speed of one train ($S_2$)= 63 mph

           Distance to be covered = 441 miles

∵ Train is running in opposite direction, so their relative speed = $(S_1 + S_2)$

Relative speed = $(35 + 63) = 98 mph$

Now, time taken to travel 441 miles apart

Time = $\frac{\textrm Distance}{\textrm relative speed}$

Time= $\frac{441}{98} = 4.5 hours$

∴ Times taken to travel 441 miles apart is 4.5 hours
