Question 614456: Doug and Austin both run on their junior high school cross country team. Doug was not feeling well and ran 2 miles per hour slower than Austin. Doug finished the four mile race 10 minutes after Austin. How fast was Austin running? How long did it take Doug to finish the race?
this is what I have but it doesn't seem to be working out
D = R x T
Doug ... 4 ... x-2 ... [4/(x-2)]+10
Austin ... 4 ... x ... 4/x

Question 614591: Question:
After driving 12 miles north and then 5 miles west, how far will you be from your starting point.
I'm not really sure if this is a trick question or something, because basicall are you just adiing 12+5=17 which would be your answer, or are you supposedly able to cut across diagonally, which would make it 12 miles.
Your help is greatly appreciated

Question 614630: Casey leaves home at 10 a.m and drives at an average speed drives at an average speed of 25 mph. Marshall leaves the same house 15 minutes later, and drives the same route, but twice as fast as Casey. At what time will Marshall pass Casey, and how far from home will they be when he does?
I tried this equation for the first question, but I got a negative number.
25t = 50(t+1/4)
