A train travelled at an average speed of 100 km/hr, stopping for 3 minutes after every 75 km. How long did it take to reach its destination 600 km from the starting point? |
|
Answer» 6 HRS 21 min Time taken to TRAVEL 600 km = Distance/Speed =600/100 = 6 hour It means train stops 7 times before 600 km and 1 time just after 600 km. Hence we need to TAKE only 7 stops into consideration for the 600 km travel. Hence, total stopping time in the 600 km travel = 7 x 3 = 21 minutes Total time needed to reach the destination = 6 hours + 21 minutes = 6 hrs 21 min |
