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.
How many hours did Suzette run?
How many hours did she bike?
How is this done? I have no idea what the steps are.
