Answer:
6 hours
Step-by-step explanation:
total: 540 mi
drove motorcycle: 40mph
drove car: 60 mph
11 hours
equation for miles: 540=40x+60y
equation for time: 11=x+y
11=x+y
-x -x
y=-x+11 <---- plug in
540=40x+60(-x+11)
540=40x-60x+660
-660 -660
-120=-20x
/-20 /-20
x=6
6 hours
<span>Always perform the same operation to both sides of the equation. When you multiply or divide, you have to multiply and divide by the entire side of the equation. Try to perform addition and subtraction first to get some multiple of x by itself on one side.</span>
