Question

Algebra word prob.... please help!
You have family that lives directly north of New York and your friend that lives next door to you has family that lives directly east of New York. On a map you figured out that your destinations are exactly 300 miles apart. On the day before thanksgiving you leave at 7 am, driving a consistent 45 mph, and your friend leaves at 9 am driving a consistent 40 mph, and you both arrive at your destinations at the same time. How long after you car starts traveling does it take for you both to be at your destination?

I have to go now, but if you think of something please just type it up for me... I don't know, I tried making a right triangle... but that didn't work very well. Thanks!

Answer 6

Well, looking at this, it doesn't make sense; its impossible for them to arrive at the same time; the one with the higher rate departs first, yet they arrive at the SAME time?....

Answer 7

However, if we were to disregard that statement, we may find how long it takes each individual to reach the destination by equations:
300=45x+90 (Your departure)
300=40x (Your friends)
