find the unit rate

Question

45 kilometeres in 3 hours=_____________ kilometers per hour

Answer 1

To find the unit rate, you divide the total distance by the total time.

In this case, you have 45 kilometers traveled in 3 hours.

Unit rate = \( \frac{45 \text{ kilometers}}{3 \text{ hours}} = 15 \text{ kilometers per hour} \)

So, the unit rate is 15 kilometers per hour.
