One car moving on a straight road covers one third of the distance with 20 km/hr and the rest with 60 km/hr. The average speed is
Text Solution
Verified by ExpertsThe correct answer is:
D
Average speed \(\frac{\text{Total distance}}{\text{Total time}}\) \(= \frac{x}{t_1 + t_2}\)
\(- \frac{x}{\frac{x}{V_1 13} + \frac{2x}{V_2 13}}\) \(= \frac{1}{\frac{1}{3 \frac{1}{20}} + \frac{1}{3 \frac{1}{60}}} = 36 \ km/hr\)
