Brendan ran a total of 8 miles over the course of 4 track practices.​How many track practices would it take for Brendan to run 10 miles? Solve using unit rates.

Answer 1

To find the number of track practices Brendan would need to run 10 miles, we can set up a proportion using unit rates:

8 miles / 4 practices = 10 miles / x practices

Cross multiplying, we get:

8 * x = 4 * 10

8x = 40

Dividing both sides by 8:

x = 40 / 8

x = 5

Thus, it would take Brendan 5 track practices to run 10 miles.
