Step-by-step explanation:
Answer:
Step-by-step explanation:
Given as :
The distance cover while running =
= 5 miles
Let The speed for running = 
The distance cover with bike =
= 80 miles
The speed for biking =
= 15 mph + 
Total Time taken = 5 hours
Now Time = 
∴ 5 hour =
+ 
Or, 5 hour =
+ 
Or, 5 hour = 
or, 5 × (
) = 
Or,
-
= 0
or,
= 0
or,
= 0
Or,
= 0
Or,
= 0
Or,
= 0
∴
= 3 , - 5
So, the running speed = 3 mile per hour
And the biking speed = 15 mph + 3 mph = 18 mile per hour
Hence The running speed of Stu is 3 mile per hour . Answer
