A car travels 60 km in the first 2 hours and 68 km in the next 2 hours. What is the car’s average speed?
2 answers:
<u>Answer:</u> The average speed of the car is 32 km/hr
<u>Explanation:</u>
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:
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:
Hence, the average speed of the car is 32 km/hr

Answer:
The time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s is 0.84 seconds.
Explanation:
Given that,
Acceleration of the car,
Initial speed of the car, u = 24.6 m/s
Final speed of the car, v = 26.8 m/s
We need to find the time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s. The acceleration of an object is given by :
t = 0.84 seconds
So, the time taken by the car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s is 0.84 seconds. Hence, this is the required solution.
