Distance As A Function Of Time
Suppose a vehicle travels at a constant speed of 30 miles per hour. Let x represent the number of hours traveled and y represent the total distance traveled in miles. Since y is determined by x, y is a function of x. Which of the following equations represents this function?
A
None of the above
B
y = 30x
C
y = 30 + x
D
y = x - 30
