40*4 = 160

55*4 = 220

So he legally traveled between 160 and 220 miles

The minimum speed for vehicles on a highway is 40 mph, and the maximum is 55 mph. If Philip has been driving nonstop along the highway for 4 hrs, what range in miles could he have legally traveled?
----------------------
Hint: Use the formula distance = time * rate
The range of rate: 40 < r < 55
If time is 4 hrs
Then the range of distance: Min. distance < d < Max. distance
You can plug the numbers in.
Hope it helps! John
