Answer:
39.9 minutes
Explanation:
Speed of man = 4 km/hr
Time = 2 hr 45 min = 2.75 hr
Hence, distance covered by man = Speed * Time = (4 * 2.75) km = 11 km
Speed while running = 16.5 km/hr
Distance covered = 11 km
Hence, time taken = Distance / speed = 11 / 16.5 = 0.66 hr = 39.9 minutes
Explanation:
Speed =4 km/h
Time = 2hr +45/60 h
= 2 hr + 3/4
=2+.75
=2.75 h
Distance covered = speed × Time
= 4×2.75
= 11 km
Now time taken to cover this distance at the speed of 16.5km/h
Time =distance /speed
= 11/16.5
Time =0.6 h
