A car travels 243 km in the first hour and 225 km in the second hour. What is the average speed (in km/h) of the car for the whole journey?

Correct option is A

Given:

Distance in 1st hour = 243 km

Distance in 2nd hour = 225 km

Total time = 2 hours

We need to find average speed.

Formula Used:

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

Solution:

Total distance = 243 + 225 = 468 km

Total time = 2 hours

Average Speed=$$\frac{468}{2} = 234 \, \text{km/h}$$​
