A car travels 187 km in the first hour and 77 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 in 1st hour = 187 km

Distance in 2nd hour = 77 km

Total time = 2 hours

We need: Average speed of the car (km/h).

Formula Used:

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

Solution:

Total distance = 187 + 77 = 264 km

Total time = 2 hours

Average Speed $$= \frac{264}{2} = 132 \, \text{km/h}$$​​
