A car travels from A to B at a speed of \(20 \text{ km/hr}\) and returns at a speed of \(30 \text{ km/h}\) . The average speed of the car for the whole journey is
Text Solution
Verified by ExpertsThe correct answer is:
B
Distance average speed \(= \frac{2 v \cdot v_{z}}{v \cdot + v_{z}}\) \(-\frac{2 \times 20 / 30}{20 + 30}\)
\(-\frac{120}{5} - 24 \text{ km/hr}\)
