If a plane is going 630 mph, how long will it take to go 7560?

Your answer is A. 8/45 mph

Step-by-step explanation:

I can provide a more detailed answer in a few but for starters, you can rule out answers C & D because that would be the fastest snake alive to be able to travel that far in such a short time.

That leaves a choice between A or B. Using the common denominator method to switch 2/9 and 4/5 to x/45, this makes the most sense. When comparing the 8/45 mph to the actual question, it's very reasonable.

I'll come back in a few and provide the actual math. I'm late for the doctor.

Good luck! Hope this helps!
