5. If the time taken by a boat to travel 180 km upstream and 80 km downstream is 5 hours.Find the time taken by the boat to cover 126 km upstream and 56 km downstream.
   5.5 hours
   3.5 hours
   4.9 hours
   2.2 hours
   1.5 hours
   Option B
   Let the upstream and downstream speed be x km/hr. and y km/hr. resp.
   180/x + 180/y = 5
   Multiply both sides by 7/10, we get
   126/x + 56/y = 3.5
   Time taken = 3.5 hours
