Answer:
120 mph
Step-by-step explanation:
Distance = rate * time
D = 70 miles
t = 35 minutes
So that gives us:
70 mi = r(35 min)
Divide both sides by 35 min:
70/35 mi/min = r
simplify:
2 mi/min = r
If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:
2 * 60 = 120
120 mph = r
The slope of the function would be 1.5. This slope represents that each ride costs $1.50. The starting price is $4.
