Answer:
x=7
Step-by-step explanation:
expand 4(x+5): 4x+20
2x+34=4x+20
subtract 34 from both sides
2x+34-34=4x+20-34
2x=4x-14
subtract 4x from both sides
2x-4x=4x-14-4x
-2x=-14
divide both sides by -2
-2x/-2=-14/-2
x=7
Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
