2.3 hours, or 2 hours & 18 minutes
Step-by-step explanation:
we are trying to find h when d is 56.68, so I replaced d with 56.68

subtract 0.1 from both sides

divide both sides by 24.6
Answer:
rate of motorboat: b
rate of current: c
So the rate the boat travels upstream is $b - c$, and the rate it travels downstream is $b + c$
Step-by-step explanation:
d = rt
200 = (b - c)\cdot 5
200 = (b + c)\cdot 4
b - c = 40
b + c = 50
Adding these equations, we get:
2b = 90
b = 45
So
c = 50 - 45 = 5
<u>Therefore the rate of the boat is 45kph, and the rate of the current is 5kph</u>

1 dozen = 12 apples.
3 apples cost 0.48, multiply that by 4 to get the price of 1 dozen.
0.48 x 4 = $1.92 per dozen.
Divide the total you can spend ( 3.84) by cost per dozen:
3.48 / 1.92 = 2
You can buy 2 dozen.
