Murphy is doing a duathlon which consists of a 10-mile running portion and a 40-mile biking portion. Enter an equation that shows the pace, in minutes per mile, that Murphy needs to run (r), as well as the pace, in minutes per mile, that he needs to bike (b) in order to complete the duathlon in 220 minutes.

don't give

stops on an even number.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
