Question

If a car's odometer is set to zero at the beginning of a trip and half an hour later it reads

44 km, what is the car's average speed in km/h?

Answer 1

The car's average speed over the half-hour trip was 88 km/h, calculated by dividing the total distance of 44 km by the time taken, which is 0.5 hours.

Step-by-step explanation:

To find the car's average speed in km/h, we need to divide the total distance traveled by the time taken for the trip. Given that the odometer reading changed by 44 km over a half-hour period, we can calculate the average speed using the formula:

Average speed = Total distance / Time taken

Converting half an hour into hours, we have 0.5 hours. So, the average speed is:

Average speed = 44 km / 0.5 h = 88 km/h

Therefore, the car's average speed was 88 kilometers per hour during the trip.
