Ryan is riding his bike. He biked a distance of 12 miles at a rate of 4 miles per hour. Rearrange the distance formula, d = rt, to solve for Ryan's time in minutes. (1 hour = 60 minutes)

Question

480 minutes
180 minutes
8 minutes
3 minutes

Answer 1

The distance formula d = rt can be rearranged to solve for time as follows:

t = d / r,

where t is the time in hours, d is the distance in miles, and r is the rate in miles per hour.

In this case, the distance is 12 miles and the rate is 4 miles per hour. Therefore,

t = 12 / 4 = 3 hours.

Since 1 hour is equal to 60 minutes, we can convert the time in hours to minutes by multiplying by 60:

3 hours * 60 minutes/hour = 180 minutes.

Therefore, Ryan's time in minutes is 180 minutes.

So, the correct answer is:

180 minutes.
