The distance d in miles that a car travels in t hours at a rate of 58 miles per hour is given by the equation d=58t. What is the best estimate of how far a car travels in 7 hours?
The car travels
We are already given an equation, with
#color(blue)d = 58color(red)t#
Now we can plug in
#color(blue)d = 58(color(red)7)#
Now simplify to find the desired distance.
#color(blue)d = color(blue)(406)#
