Anna wants to finish a 26.2 mile race in 5 hours. if she runs the first 3 hours of the race at a speed of 6 miles per hour, what must her speed be for the rest of the race

First off you need to multiply 6 by 3 for how many miles she went and then divide the leftover total by two (For the last two hours) to realize she needs to run 4.1 mph.

Hope this helped :)

Wow. that is a really cool question.
