You've probably seen speed as miles per hour before. It's distance over time. To compare the speeds of the two runners, we will first need to actually calculate their speeds.
Maura runs 5 miles in 1.25 hours, or [tex] \frac{5}{4} [/tex] hours.
We write [tex] 5 \ mi \ * \frac{5}{4} \ hr = \frac{25}{4} \ mi/hr = 6.25 \ mi/hr[/tex].
Ava runs 3 miles in 0.83, or [tex] \frac{5}{6} [/tex] hours.
We write [tex]3 \ mi \ * \frac{5}{6} \ hr = \frac{5}{2} \ mi/hr = 2.5 \ mi/hr[/tex], probably more my speed.
Maura runs faster here.
