Answer:
for me it will be 12 hours and 30 minutes (12.5 hours) because if i divide 40 into 10 it will be 4 actually and its possible to get 10 by multiplying 4 but it was in decimal form that 2.5 so 10 kph is 2.5 hr, 20 kph is 5 hr, 3 kph is 7.5 hr, 4 kph is 10 hr and 50 kph is 12.5 or in time 12 hours and 30 minutes.
