Driving at an average speed of 52 mph, how
long will it take someone to take a 390 mile
road trip

It'll take 7 and a half hours.

Step-by-step explanation:

this situation can be expressed by the equation 52x=390, where x is how long it took to drive 390 miles.

x=390/52=7.5

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
