A boat can row 14 km/h in still water and the speed of the current is 2 km/h. Find the time taken to row 36 km upstream. MCQ with Answer and Explanation

Explanation:
Speed of truck = 240 / 4 = 60 km/h. Time taken for 180 km = 180 / 60 = 3 hours.

Explanation:
By 9:00 AM, Train P has tracked for 1 hour, covering 45 km. Remaining route segment gap separation = 300 - 45 = 255 km. Relative speed index = 45 + 55 = 100 km/h. Time after 9:00 AM = 255 / 100 = 2.55 hours = 2 hours 33 minutes. Meeting time is 11:33 AM.

Explanation:
Speed = 72 * (5/18) = 20 m/s. Total distance in 18 seconds = 20 * 18 = 360 meters. Train length + Platform length = 360 => Train length + 160 = 360 => Train length = 200 meters.
