A car starts moving on a straight road. It makes the entire journey in three parts. The total time of journey is 25 s. For first part it accelerates at a constant rate `5m//s^(2)`. For second part it moves with a constant speed. For the third part it retards at constant rate `5m//s^(2)` to come to rest.
Let `t_(1)` be the time for first part, `t_(2)` be the time for 2nd part then correct relation is

Options

A. `t_(2)=25-t_(1)`
B. `t_(2)=25-2t_(1)`
C. `2t_(2)=25-t_(1)`
D. None of these

Answer

B
