In a race, there are 4 members in a team. Each member has to cover 5 km one after another. If the total time taken is 30 minutes, then what would have been the average speed? |
$50\frac{km}{hr}$ $40\frac{km}{hr}$ $50\frac{m}{sec}$ $40\frac{m}{sec}$ |
$40\frac{km}{hr}$ |
Total distance = 5 + 5 + 5 + 5 + 5 = 20 km Total time taken = 30 minutes = 0.5 hour Average speed = \(\frac{20}{0.5}\) = 40 km/hr |
