Question 898330
If I'm driving 276 miles at 70 mph, how long will it take me to reach my destination? 
the equation is "the distance formula":
d = rt
where
d is distance traveled (276)
r is rate or speed (70 mph)
t is time (what you're looking for)
.
substitute what you know:
276 = 70t
276/70 = t
3.943 hours = t
or 
3 hours and 57 minutes
