Step-by-step explanation:
The fuel efficiency is given by :

We need to find the fuel efficiency for a speed of 30 mph
Put the value of s equals 30 mph in the above equation.

So, the required fuel efficiency is equal to 17.67 mpg.
Positive because you will said that has the charged is about $2.50
Answer:
All lines, with a value for the slope, will have one zero.
Step-by-step explanation:
To find the zero of a linear function, simply find the point where the line crosses the x-axis. Zeros of linear functions: The blue line, y=12x+2 y = 1 2 x + 2 , has a zero at (−4,0) ; the red line, y=−x+5 y = − x + 5 , has a zero at (5,0) .
345 mi; if you travel 69 miles per hour, and drive 5 hours, you have to multiply 69 and 5 to find how far you travel in 5-- 69 times 5 is 345.
