Question 86448
(rate)(time) = (rate)(time)
time Wed. = 3/4 hr.
time Thur. = 36 min. = 3/5 hr.
rate Thur. = 12 + rate Wed.
use a variable for rate Wed.
plug the resulting expressions into the above algorithm for the rates
plug 3/4 and 3/5 in for the times
solve the resulting equation for the variable
