Both car A and car B leave school at the same time, traveling in the same direction. Car A travels at a constant speed of 79 km/h, while car B travels at a constant speed of 89 km/h.
How far is Car A from school 2.1 h later?
Answer in units of km
Multiply Car A's speed by the elapsed time.
The information about Car B is obviously not needed to answer the question.
