Answer:
D) 1.0 mph
Step-by-step explanation:
Own speed the boat = x
rate(speed) of the current = a
Speed of the boat downstream = (x + a)
Speed of the boat upstream =<em> (x - a)</em>
Speed of the boat downstream = 40 mi/4 h = 10 mi/h
Speed of the boat upstream = distance/time = 40 mi/ 5 h = <em>8 mi/h</em>
<em />
x + a = 10
<u>x - a = 8</u>
2x = 18
x = 9
x + a = 10
9 + a = 10
a = 1 mi/h
