# What will be his Speed? If

A man has to cover a distance of 6 km. in 45 minutes. If he covers one-half of the distance in 2/3rd time, what should be his speed to cover the remaining distance in the remaining time?

- 12 km/hr
- 14 km/hr
- 8 km/hr
- 10 km/hr

**Answer: (1) 12 km/hr**

**Explanation:-**

Total distance covered by a man in 45 minutes = 6 km

Time = 45 min = 45 /60

= 3/4 hr

Then, speed = 6 x 4/3

= 8 km/ hr

one – half of distance = 6/2 = 3 km

2/3 rd of time = 3 x 2 / 4 x 3

= 1/2 hr

Remaining time = 3/4 – 1/2

= (3 – 2)/4

= 1/4 hr

Remaining distance = 6 – 3 = 3 km

Speed = 3 x 4/1

= 12 km/hr

Hence, the answer is (1) 12 km/hr
