Question

Two people started from the same point at the same time and traveled in opposite directions. One traveled at 60 mph and the other at 50 mph. How long will it take before the two people are 440 miles apart?

Answer 1

You can set this up as the following equation
x = hours
60x + 50x = 440
110x = 440
110x / 110 = 440/110 = 4

It will take 4 hours
60x+ 50x = 440
60(4) + 50(4) = 440
440 = 440
