A train 575 m long crosses a tunnel of length 325 in 90 sec. What is the speed of the train in kmph
34 kmph
35 kmph
28 kmph
36 kmph
Explanation:
Total distance traveled = Length of train + Length of tunnel = 575 + 325 = 900
Time taken to cross the tunnel = 90 sec.
Speed in kmph = distance/time *18/5
= 900/90 * 18/5
= 180/5
= 36 kmph
Total distance traveled = Length of train + Length of tunnel = 575 + 325 = 900
Time taken to cross the tunnel = 90 sec.
Speed in kmph = distance/time *18/5
= 900/90 * 18/5
= 180/5
= 36 kmph
