Question

A person has to cover a distance of 290 km in 15 hours. If he covers 7/10 of the distance in 3/5 of the time, then what should be his speed (in km/hr) to cover the remaining distance in the remaining time?​

Answer 1

Answer:

He covered 203km in 9 hours and has to cover 87km in 6 hours.

$\frac{87}{6} = \frac{29}{2} = 14.5$

Therefore, person has to go at minimum 14.5km/h to cover remaining distance in remaining time.

Hope it helps
