Question 341165: Kim starts to walk 3 mi to school at
7:30 A.M. with a temperature of 0°F. Her brother Bryan
starts at 7:50 A.M. on his bicycle, traveling 10 mph faster
than Kim. If they get to school at the same time, then how
fast is each one traveling?

You can put this solution on YOUR website!
I don't see what the temperature has to do with it other than it was a cold walk to school.
Since d=rt, Kim travels 3=rt.
Bryan starts 1/3 hour later and travels 10 mph faster, but he travels the same distance: 3=(r+10)(t-1/3)
There are two equations with two unknowns. Can you finish now?.
