A car travels 209 km in the first hour and 157 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 covered in the first hour = 209 km

Distance covered in the second hour = 157 km

Total time taken = 2 hours

Formula Used:

Average Speed =$$\frac{\text{Total Distance}}{\text{Total Time}}$$​​

Solution:

The total distance covered by the car is:

Total Distance = 209 + 157 = 366 km

The total time taken for the journey is given as 2 hours.

Average Speed= ​$$\frac{366}{2} = 183 \, \text{km/h}$$

The average speed of the car for the whole journey is 183 km/h.
