1. Laxman has to cover a distance of 6 km in 45 minutes . If he cover one half of the distance in 2/3rd time . what should be his speed to cover the remaining distance in the remaining time?
1. 12 km/hr.
2. 16 km/hr.
3. 3 km/hr.
4. 8 km/hr.
##### Correct Option: C

∵ Time left = (1/3 X 45/60) hr.
= 1/4 hr.
Distance left = 3km

∴ speed required = [3 / (1/4) ] km/hr.
= 3 x 4
=12km/hr .
