Step-by-step explanation:
During the Boston Marathon, a What are the unit rates for this situation? (How far can they run in 1 hour and how long does it take to run 1 mile?)
If a certain runner averages running 25 miles in 5 hours, then
25miles = 5hrs
To determine how far they can run in 1 hour, then;
X = 1hr
Divide both expressions
25/x = 5/1
5x = 25
X = 5miles
Hence the runner can run 5miles in an hour
Similarly if
25miles =1hr
1mile = y
25y = 1
Y = 1/25
Y = 0.04hrs
Hence the time taken to run 1mile is 0.04hrs
