A) 45 s
B) 40 s
C) 35 s
D) 30 s
Correct Answer: D
Solution :
To cover a distance by train \[=280+220=500\,m\] Speed of train \[=60\,\text{km/h}\] \[=\frac{60\times 1000}{60\times 60}=\frac{50}{3}\text{m/s}\] \[\therefore \] Time taken by tram \[\text{=}\frac{\text{Total distance}}{\text{Speed}}\text{=}\frac{\text{500}}{\text{50/3}}\text{=30}\,\text{s}\]You need to login to perform this action.
