Question

A car traveling on a highway is 60 miles away from home after 1 hour, and is 300 miles away from home after 5 hours. What is the rate of change of the car’s distance over time?

Answer 1

I think its 5mph because when we make a function

f(x)=60x

f(1)=60
f(2)=120
f(3)=180
f(4)=240
f(5)=300
You're Just adding 60 so every hour it increases by 60 mph
