A car travels 106 km in the first hour and 276 km in the second hour. What is the average speed (in km/h) of the car for the whole journey?

Correct option is B

Given:

Distance covered in the first hour = 106 km

Distance covered in the second hour = 276 km

Formula Used:

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

Solution:

Total Distance = 106 + 276 = 382 km

Total Time = 1 + 1 =2 hours

Average Speed $$= \frac{382}{2} = 191 \, \text{km/h}$$​​

Thus, the average speed of the car for the whole journey is 191 km/h.
