Answer:
The ride will take 2 h
Step-by-step explanation:
From the question,
Deon plans to ride a 20-mi bicycle trail, that is the total distance he plans to cover is 20-mi
Distance, d = 20 mi
Also, his average speed is 10 mi/h
rate of speed, r = 10 mi/h
To determine how many hours the ride will take,
From the formula,
d = rt
where
d is the distance covered
r is the average rate of speed
and t is the time.
We can solve for t, such
d = rt becomes
t = d/r
Now, from the question
d = 20 mi
r = 10 mi/h
∴ t = (20 mi) / (10 mi/h)
t = 2 h
Hence, the ride will take 2 h (hours)
From inspecting the graph, you can identify the y-intercept and the slope of the line shown.
The y-intercept is 200 gallons.
The slope is
75-200
m = ------------- = -12.5 gallons/minute
10 - 0
Thus, y = 200 gallons - [12.5 gallons/minute ]t
To answer the 2nd question, let t = 12 minutes and calculate y(12).
To determine how long it wld take to empty the tank, set the above formula equal to zero and solve the resulting equation for t.
