Assume 2 individuals live 350 miles apart, both people get into their cars at 8am and travel towards one another with driver A going 15miles and hour faster than driver B if they pass each other at 11am how fast was driver A going

Solution:

Driver A: x

Driver B: x-15

So

3x+3(x-15)=350

x = 65.83 mph

So Driver A's speed is 65.83 mph
