Speed-stream (y) in relation to the speed of the boat (x) -2 equations:
216 / (x + y) = 5
5x + 5y = 216
y = (216 - 5x) / 5
216 / (x - y) = 10
108 / (x - y) = 5
5x - 5y = 108
y = (5x - 108) / 5
Speedboat-x:
216 - 5x = 5x - 108
10x = 324
x = 32.4
Current speed 1 Equation:
= (216 - 5 [32.4]) / 5
= (216 - 162) / 5
= 54 / 5 or 10.8
Response: boat speed, 32.4 km / h, traffic speed, 10.8 mph
Test (10 hours travel dates):
= 216 m / (32.4 to 10.8 km / h)
= 216 mph mi/21.6
= 10 hours

SPD Dist Total = average time / Total
SPD = 216/10
= Boat 21.6mi/hr
Sorry, I do not know how to present
someone please answer my question!
