Answer:
12 km
Step-by-step explanation:
Let
x km/h = speed of the canoe on the lake
y km/h = speed of the current
<u>With the current:</u>
Speed = x + y km/h
Distance = 30 km
Time = 3 hours 20 minutes = 
hours
Thus,
<u>Against the current:</u>
Speed = x - y km/h
Distance = 28 km
Time = 4 hours
Thus,
Add these two equations:
<u>On the lake:</u>
Time = 1.5 hours
Speed = 8 km/h
Distance 
Answer:
0.6%?

Answer:
Total revenue = 13.5 + 9 = $22.5
Step-by-step explanation:
The toll charges $1.00 for passenger cars and $2.25 for other vehicles. During daytime hours 60% of all the vehicles are passenger vehicles.
A particular daytime period 15 vehicle crossed the bridge. Recall that during daytime period, 60% of all the vehicles are passenger vehicles . Therefore,
Passenger vehicles = 60% of 15
Passenger vehicles = 60/100 × 15
Passenger vehicles = 900/100
Passenger vehicles = 9
9 of the vehicles are passenger vehicle and the charges for passenger cars is $1.00. other vehicle is $2.25.
revenue for passenger cars = 1 × 9 = $9
revenue for other vehicles = 2.25 × 6 = $13.5
Total revenue = 13.5 + 9 = $22.5
Answer:using the square root on both sides of the equation
Step-by-step explanation:
