A car enters a turnpike 22 miles north of a town. The car travels north at an average speed of 64 miles per hour. How far is the car from the town after 4 hours?

How do you solve the linear function then solve the problem?

If you could help me understand this it would be amazing because I have a test soon and I actually want to know how to do it.

22 + distance traveled after entering pike

= 22 + 4 * 64

= 22 + 256

= 278 miles

This is just like the taxi problem really.
Answered by Damon
You are already 22 miles north
then
you travel 4 * 64 miles
Answered by Damon
y = m x + b
here
distance = 4 (speed) + 22

Distance is a function of time. The constant rate of change is 64. Write the equation y = 64x + 22. Substitute 4 in for x to get 278 miles.
