Q. 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?
✅ Correct Answer: (C)
3 km/hr.
Explanation: ∵ 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 .
= 1/4 hr.
Distance left = 3km
∴ speed required = [3 / (1/4) ] km/hr.
= 3 x 4
=12km/hr .
