Answer 21

Suzette ran and biked for a total of 34 mi in 3.5 h. Her average running speed was 6 mph and her average biking speed was 12.5 mph.
Let x = total hours Suzette ran.
Let y = total hours Suzette biked.
Use substitution to solve for x and y. Show your work. Check your solution.
(a) How many hours did Suzette run?
(b) How many hours did she bike?

Answer 22

maybe just help me through this one

Answer 23

So I would assume you would write
\[6x+12.5y=34\]
and
\[x+y=3.5\]
you can use system of equations which you get 1.5 hours ran and 2 hours biked
