Question

A car travels first half of the distance with a velocity \(V\) and second half of the distance with a velocity \(3V\), then the average velocity is

• A. \(2V\)
• B. \(3V\)
• C. \(4V\)
• D. \(1.5V\)

Hint:

For equal distances covered at speeds \(v_1\) and \(v_2\), use \[ v_{\text{avg}} = \frac{2v_1v_2}{v_1+v_2}. \] Here, \[ v_{\text{avg}} = \frac{2(V)(3V)}{V+3V} = \frac{3V}{2}. \]

Answer 1

The Correct Option is D
