Question

A delivery driver is tracking a total of 250 miles from a warehouse to a store at an average speed 45 miles per hour. The function f(x)=250-45x represents the distances remaining in miles after traveling for x hours

Answer 1

The equation f(x) = 250 - 45x represents the distances remaining in miles after traveling for x hours, assuming a constant average speed of 45 miles per hour.

Step-by-step explanation:

The given equation f(x) = 250 - 45x represents the distances remaining in miles after traveling for x hours.

Here's how to interpret it:

The initial distance is 250 miles because f(x) is equal to 250 when x is zero.

For every hour of travel (x increases by 1), 45 miles are subtracted from the initial distance.

This equation assumes a constant average speed of 45 miles per hour throughout the journey.

For example, if the driver has been traveling for 2 hours (x = 2), the remaining distance can be calculated as

f(2) = 250 - 45(2)

= 160 miles.
