Answer: 1500
Step-by-step explanation:
we can translate the sentence into an easy equation:
72/100 * x = 1080
Then we can solve for x by multiplying by 100/72. But wait! That can be simplified! We can cancel 4 out of both the top and the bottom to get the equivalent fraction, 25/18.
x = 1080 * 25/18
1080 and 18 can cancel since 1080/18 = 60
x = 60 * 25/1 ==> x = 1500
Average speed is total distance over total time. The total distance is 15 miles, and the total time is 1/4 hour. So 15 miles divided by 1/4 hour is 60 miles / hour.
