Question 1018645
you have 10 minutes and 2 miles to go.
Your top speed is 8mph, this is, 8 in 1. Let's convert to minutes, your top speed is 8 in x minutes (however many minutes there are in 1 hour, you figure it out).
That means you can do 8/2=4 miles in 1/2 hour (convert it to minutes). And if we half that again, you can do 4/2 = 2 miles in 15 minutes. You only have 10 minutes. You'll be 15-10= minutes late to class.
We just did this problem in our heads. Not bad, huh?
