A car travels 272 km in the first hour and 294 km in the second hour. What is the average speed (in km/h) of the car for the whole journey?

Correct option is C

Given:

Distance traveled in the first hour = 272 km

Distance traveled in the second hour = 294 km

Formula Used:

Average speed =$$\frac{\text{Total distance}}{\text{Total time}}$$​

Solution:

Total distance = 272 + 294 = 566 km

Total time = 1 + 1 = 2 hours

Average speed =$$\frac{566}{2} = 283 \, \text{km/h}$$​

Thus, the average speed of the car for the whole journey is 283 km/h.
