Answer 2

Answer:

1 question D 20 min

2 question A 6 h

Step-by-step explanation:

Let the total distance to be covered is 36 kms.

Time taken to cover the distance without stoppage = 36/18 hrs = 2 hrs

Time taken to cover the distance with stoppage = 36/12 = 3 hrs.

Thus, he takes 60 minutes to cover the same distance with stoppage.

Therefore, in 1 hour he stops for 20 minutes.

When distance is constant, by the rule of proportionality

Given that is 2 *

Therefore

time of B = 6 h
