Answer:
Isabella would have gone 270 miles in 180 minutes.
Explanation:
60 times 3 = 180
There are 60 minutes in one hour, and there are three hours.
180 divided by 30 = 6
180 is divided by 30 because the rate of speed we know is 45 miles in 30 minutes.
45 times 6 = 270
There were 6 30s in 180, so 45 is multiplied by 6.
hope this helps
