Answer:
rate 72 mph; current 16 mph
Step-by-step explanation:
to find the rate of the boat and the current we can model the equation like this
let r = rate
let c = current
8(r - c) = 464
6(r + c) = 540
8r - 8c = 464
6r + 6c = 540
r - c = 58
r + c = 90
then you could use elimination to find r
2r = 148
r = 74
the rate is 74 mph
then plug it in
the current is 16 mph
