Given:
1st case:
Time=2hours 45min = 2 (45/60)
= 2 ¾= 11/4 h
Speed= 4 km/h
Speed = Distance/time
Distance= speed × time
Distance= 4 ×(11/4)= 11 km
Distance = 11 km
2nd case
Given:
Speed= 6.5 km/h
Distance= 11 km (he has to cover same distance as in 1st case)
Time = Distance/speed
Time= 11/6.5= 110/65= 22/13h
Time = 22/13 h = (22/13) × 60 = 1320/13 = 101.53 = 102 minutes (approx)
Time= 1h 42 min or 102 min.
Hence, he will take 1h 42 min or 102 min to cover the same distance.

in 2 hr men covers 4×2.5 = 10 km
if he use cycle
10km ÷ 12
it will take 50 minutes
if he use cycle
10km ÷ 12
it will take 50 minutes
