Solve the problem.
-The time it takes to travel a given distance at constant speed is given by the formula t $= \frac { \mathrm { d } } { \mathrm { r } }$ where t is the time, d is the distance, and r is the rate of travel. At 60 miles per hour, what distance can be traveled in 4 hours?
A) 120 mi
B) 240 mi
C) 480 mi
D) 48 mi

Using the formula $t = \frac{d}{r}$, we can rearrange it to solve for distance $d = t \times r$. Substituting $t = 4$ hours and $r = 60$ miles per hour, we get $d = 4 \times 60 = 240$ miles.
