Two trains are moving at 45kmph and 70 kmph in opposite directions. Their lengths are 150 m and 100 m respectively. The time they will take to pass each other completely is?
Answer/Solution
47/6 sec
Steps/Work
70 + 45 = 115 * 5/18 = 575/18 mps
D = 150 + 100 = 250 m
T = 250 * 18/575 = 15/2 = 47/6 sec
Answer:C
D = 150 + 100 = 250 m
T = 250 * 18/575 = 15/2 = 47/6 sec
Answer:C
