Question

- A person has to cover a distance of 8 km in 45 minutes. He covers half of the distance in two
third of the total time. What should be his speed to cover the remaining distance in time
​

Answer 1

Explanation:

The person needs to cover 6km in 45minutes

Given that he covers one-half of the distance in two-thirds of the total time

⇒he covers half of 6 km in two-thirds of 45 minutes

⇒He covers 3 km in 30 minutes

Now he needs to cover the remaining 3 km in remaining 15minutes

Distance = 3 km

Time =15 minutes =1/4 hour

Required Speed =3/(1/4)=12 km/hr
