Answer 1

Answer: Acc. to me it's (d) 20/7

Explanation:

While calculating distance AB, take the velocity at point A as the initial vel. and vel. at point B as the final velocity because right now, we're calculating the distance for that particular part and hence, the values should be taken as such.

Similarly, while calculating the distance BC, we'll do the same i.e., take vel. at B as initial and at C as final vel.
