acceleration = a = (60 - 0)/(9.8)
a = 6.12 mi/hr - sec
a = (6.12 mi/hr - sec)* (1 hour/3600 sec)
a = 0.0017 mi/sec^2
Use the formula
S = VoT + (1/2)(a)(T^2)
where
S = distance travelled
Vo = initial velocity = 0
T = time travelled = 9.8 sec
a = acceleration = 0.0017 mi/sec^2
Substituting values,
S = 0 + (1/2)(0.0017)(9.8^2)
S = 0.0816 mi
S = 0.0816 mi * 5280 feet/mi = 431 feet
To find the average speed from 4 seconds to 8 seconds, you need the total distance traveled during that time interval and the total time taken. The average speed is calculated by dividing the total distance by the total time (4 seconds in this case). If you provide the distance traveled during that period, I can help you calculate the average speed.
The object's total distance traveled divided by the total time it traveled is its average speed.
Speed = Distance/Time
To find the average speed you must know the total distance traveled and the total elapsed. The distance traveled in each interval is simply the speed multiplied by the time (v x t). Thus, in the first interval you travel 120 x 1 = 120 meters, in the second interval 120 x 6 = 720 meters; therefore, the total distance traveled is 840 meters. The total time elapsed is 120 + 120 = 240 seconds. An average speed is simply the total distance traveled divided by the total time elapsed thus in this case it is 720 m / 240 s = 3 m/s.
No. If you divide a distance by a speed, you get a time, not a speed. For example, (meters) / (meters/second) = (seconds).
correct
No. The total distance traveled divided by constant speed is the time interval.

The total distance traveled by Apollo 11 to the Moon and back was approximately 477,800 miles (768,000 kilometers).
