The distance traveled by an automobile moving at a constant velocity is?

(Its speed) x (time it spends traveling).


What can change distance an object travels?

The formula for the distance traveled (assuming a constant speed) is:distance = time x speed So, any of the two factors on the right side of the equation will affect the distance.


Distance travaled in feet after 45 seconds at 60 mph?

Assuming the rate of 60 mph is constant, traveling 60 mph means you are traveling one mile per minute. Since 45 seconds is 3/4 of a minute, you have traveled 3/4 of a mile, or3,960 feet


For a car traveling at a constant rate of 60 mph the distance traveled is a function of the time traveled. how do i express this relation as a function?

D = 60T where T is expressed in hours.


What is the the constant of proportionality for the distance y traveled in miles in x hours as represented by the equation y divided by x?

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


What is a linear equation that fits this situation A car is traveling at a constant velocity After two hours the car has traveled 90 miles After five hours the car has traveled 225 miles?

With constant velocity (v) the equation for distance can be d = vt, where d is the distance traveled (in miles), and t is the time (in hours). So at t= 2 hr, d = 90 mi, solve for v = (90 mi)/(2 hr) = 45 mi/hr (or mph). Check this at 5 hours: d = (45 mi/hr)*(5 hr) = 225 mi, which checks with the original problem.


Is speed of sound proportional to distanced traveled?

No. The amplitude of the sound (and therefore its loudness) will decrease at greater distances; the speed will remain constant (assuming other factors, such as the density of air and the temperature, are constant).


Does a car traveling the logest time always travels the gratest distance?

Not necessarily. The distance a car travels is determined by its speed and the time it spends traveling. If a car is traveling at a slower speed but for a longer period of time, it may not cover as much distance as a car traveling at a faster speed but for a shorter period of time. So, the longest time does not always correspond to the greatest distance traveled.


Is the total distance traveled divided by constant speed eual constant speed?

No. The total distance traveled divided by constant speed is the time interval.
