Answer 7

Apologies for the incorrect response. Let's re-evaluate the situation.

Liam took 15 minutes to ride his bike for three miles. To find the unit rate, we need to determine how long it took him to travel one mile. We can do this by dividing the total time by the total distance.

15 minutes / 3 miles = 5 minutes/mile

Therefore, the correct answer is 5 minutes/mile.
