Question 178158
Along a certain highway, Pearl can average 100 miles in 1.5 hours
How long will it take her to drive 150 miles at the same rate?
-------------------
You can do it the hard way, and figure the mph average, or:
It's 1.5 times as far, so it'll take 1.5 times as long.
1.5 hours x 1.5 = 2.25 hours, or 2 hrs 15 minutes.
