Answer: The average speed of the car is 32 km/hr
Explanation:
Average speed is defined as the ratio of total distance traveled to the total time taken.
To calculate the average speed of the runner, we use the equation:
[tex]\text{Average speed}=\frac{\text{Total distance traveled}}{\text{Total time taken}}[/tex]
We are given:
Total distance traveled = (60 + 68) km = 128 km
Total time taken = (2 + 2) hr = 4 hr
Putting values in above equation, we get:
[tex]\text{Average speed of car}=\frac{128km}{4hr}=32km/hr[/tex]
Hence, the average speed of the car is 32 km/hr
