Question

C is a point midway between A and B. The average speed of a person from A to C is V. At what speed must he travel the remaining distance to have an average speed of 4V/3
for the whole journey?
​

Answer 1

Answer:

5/3

Explanation:

speed from A to C = v

let's take speed from c to B = X

V+X / 2 = 4v/3

V+ X = 8V/3

X=8V - 3 v / 3

X = 5v/ 3
