Answer: y=12.287
Step-by-step explanation:
Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.
Nancy's rate=27 mph
Greg's rate=45 mph
t=Greg's time
t+2=Nancy's time
Since they both traveled same distance then:
27(t+2)=45t
27t+54=45t
18t=54
t=3 hours
Greg will pass Nancy after 3 hours
4.3 x 10 to the power of 2
