f(n) = n/45 describes how long (in hours) it takes to travel n miles at 45 mph since time = distance ÷ speed.

Whereas distance = speed x time which would be f(n) equals n times 45.

It is the speed, which must be maintained at a constant value.

What are distance traveled and time traveled and rate of travel related?

Rate of travel = (distance traveled) divided by (time traveled)

Is the distance traveled a state function or path function?

Its a path function......but DISPLACEMENT is a state function.Distance depends on the path we followed from one state to another but displacement is a straight distance so it depends upon the states.

Does the total distance traveled divided by constant speed is an average speed?

No. If you divide a distance by a speed, you get a time, not a speed. For example, (meters) / (meters/second) = (seconds).

When do you use average speed to measure?

Average speed can be used to measure the distance traveled by an object when the acceleration is constant. x = v * t. When acceleration is a constant, the average speed can be plugged into the equation with time to yield distance.

What is the formula for distance traveled?

distance traveled = speed multiplied by time taken.

When the body starts from rest and attain velocity v in time t with a constant acceleration the distance traveled by the body is?

d = 1/2 a t2 where d is distance traveled a is the constant acceleration t is the time You can calculate the value of "a" by dividing "v" by "t".

What is The total distance traveled in a time interval?

If the speed is constant, then the distance is simply the speed multiplied by the time taken for the journey. This relationship is the distance/time = speed, or d/t = s. If the speed was constant, then the distance travelled is given by the integral. In both cases, the distance the area under the speed by time graph

If a body dropped from rest has a constant acceleration in free fall is the distance traveled by the body the same for each time interval?

No. Acceleration is the rate at which the speed is INCREASING. Since the speed is increasing,the distance traveled by the body in each time interval is also increasing.

What distance is traveled by a police car that moves at a constant speed of 1.5km in 5.0 minutes?

I am going to assume you meant a constant speed of 1.5km/min. speed = distance/time distance = speed x time = 1.5km/min x 5.0min = 7.5km

How will the total distance traveled by a car in 4 hrs?
