Question
Amrit and Rohan were traveling from point A to point B.
Amrit took 72 minutes longer than Rohan to reach point B. Their respective speeds were 50 km/h and 62 km/h. Determine the time taken by Rohan to travel from point A to point B.Solution
Let, the distance between point A to point B was ‘x’ km. So, x/50 – x/62 = 1.2 (31x – 25x)/1550 = 1.2 6x = 1860 x = 310 km Therefore, the time taken by Rohan to reach point B = 310/62 = 5 hours
