Answer:

Stu is running at 5 mph and biking at 20mph

Explanation:

"Expert Verified answer that was verified by a hand picked team of qualified employees" Is incorrect. If Stu runs at 5 mph, he'll finish the running in 1 hour. Add 15 to that and divide into 80 to get 4 hours of biking. Hence, Stu is running at 5 mph, and biking at 20 mph to complete everything in 5 hours. Don't know the exact equation for it, just did trial and error based off the original 3/18 answer.
