Question

A player completes his half of the race in 60 minutes and next half of the race in 40 minutes. If he covers a total distance of 1200 m, find his average speed.

Answer 1

Answer:

12 m /min  = 720 m/hr = 0.72 km/Hr

Explanation:

Total Distance = 1200 m

=> Total Race = 1200 m

Half of the Race = 1200/2 = 600m

Time Taken for 1st half = 60 mins

Speed for 1st Half = 600/60  = 10 m/min = 600 m/hr

Speed for 2nd Half = 600/40 = 15 m/Min = 900 m/Hr

Total time = 60 + 40 = 100 min

Average Speed  = 1200/100 = 12 m /min  = 720 m/hr

0.72 km/Hr

Answer 2

Answer:

Total time = 60 + 40 = 100 min

Average Speed  = 1200/100 = 12 m /min  = 720 m/hr

0.72 km/Hr
