Final answer:
Kemi's average speed to school can be found by dividing the total distance by the total time taken. An example calculation using a similar scenario showed an average speed of 40.0 km/h. The exact value for Kemi's speed would depend on the specific distance and time data for her trip.
Step-by-step explanation:
To calculate Kemi's average speed to school, we first need to define what average speed is. Average speed is defined as the total distance traveled divided by the total time taken to travel that distance. For instance, in the example provided, a student drove to the university from home, and the odometer reading increased by 12.0 km, and the trip took 18.0 minutes. To calculate the average speed, you would convert 18.0 minutes to hours (which is 0.3 hours) and divide the distance by the time:
Average speed = Total distance traveled / Total time taken
Average speed = 12.0 km / 0.3 h = 40.0 km/h
Hence, using the formula and the given example, Kemi's average speed to school can be calculated if we know the distance to school and the time it took to reach there.
