Question
A family drives their car from Coeur d’Alene to Boise for a relative’s graduation (608.33 km). The family travels at an average speed of 88.51 km/h. How long did the trip take? (please round answer to the nearest 10th)
Solution
To calculate the time it takes for the family to travel from Coeur d’Alene to Boise, you need to use the formula for time which is distance divided by speed.
Step 1: Identify the distance and speed from the problem. The distance is 608.33 km and the speed is 88.51 km/h.
Step 2: Plug the distance and speed into the formula. Time = Distance ÷ Speed
