The car is moving at 45 mph (90 for 2, 225 for 5) After 9 hrs, car will have travelled 45 x 9. (you did not expect me to do all your homework?)

If an object is traveling at a constant velocity, its acceleration is 0. Even if it traveled for 2 years.
110=2hrs 110 x 2=4hrs 4hrs=220 110/2 =55 55=1hr 220+55=275 275=5hrs {cloud9}
D = 60T where T is expressed in hours.
Assuming that the car moves at a constant speed, you can use the standard formula for speed: distance = speed x time

(Its speed) x (time it spends traveling).
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.
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
D = 60T where T is expressed in hours.
It is the speed, which must be maintained at a constant value.
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.
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).
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.
No. The total distance traveled divided by constant speed is the time interval.
