A car has to cover a distance of 288 km in 20 hours. If it covers half of the journey in 1/5th of the time, find the speed to cover the remianing distance in the time left.

9km/hr

Total distance to be covered = 288km

Time = 20 hours

 It covers half of the journeyin 1/5th of the time,

remaining distance = 144 km, remianing time = 16 hours

Speed of the remaining journey = $\frac{distance}{time}$

                                               =  $\frac{144}{16}$ = 9 km/hr
