To determine the time it would take Aaliyah to run 7 miles, we can set up a proportion relating the distance and time of her run:
5 miles / 45 minutes = 7 miles / x minutes
where x is the time it would take her to run 7 miles.
To solve for x, we can cross-multiply and simplify:
5 miles * x = 45 minutes * 7 miles
5x = 315
x = 63 minutes
Therefore, it would take Aaliyah 63 minutes to run 7 miles.
To determine the time it takes for her to run a marathon, which is approximately 26 miles, we can use the same proportion:
5 miles / 45 minutes = 26 miles / y minutes
where y is the time it would take her to run a marathon.
To solve for y, we can cross-multiply and simplify:
5 miles * y = 45 minutes * 26 miles
5y = 1170
y = 234 minutes
Therefore, it would take Aaliyah 234 minutes (or 3 hours and 54 minutes) to run a marathon.
