Meed velocity first.
V = delta X/delta t
V = 50 m/30 s
= 1.666 m/s
now, acceleration
A = delta V/delta t
A = 1.666 m/s/30 s
= 0.056 m/s2
============
It's a bad question because 5 meters per second per secondis not"a constant speed"it is a rate of acceleration.5 x 5 = 25 meters traveled.
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
Speed is constant. Acceleration is zero.
The average speed = 1/2 (initial speed + final speed) = 1/2 (15 + 25) = 1/2 (40) = 20 meters per second.The distance traveled = (average speed) x (time) = (20 x 7) = 140 meters.
The short answer is about a tenth of a second less or 21.97 seconds assumptions: object is moving at a constant speed and 22.1 is a value in seconds 220 yards = 660 feet 200 meters = 656.17 feet 3.83 = feet less to travel 21.1/660 = time to travel one foot ((21.1/660) * 3.83) - 22.1 = 21.97 seconds to travel 200 meters

60.912 meters in that time
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
The answer will depend on the measurement units used for 36 (time?) and the units for acceleration.

Speed is constant. Acceleration is zero.
Usually measured in seconds (m/s2), you can measure it in hours or minutes, but those units of time must be translated into seconds, ie: The turtle has an acceleration of 45meters/70minutes ; 60 seconds in one minute, 60 x 70 = 4200 seconds = 45metes/4200 seconds. Therefore the turtle can travel 45 meters every 4200 seconds.
The average speed = 1/2 (initial speed + final speed) = 1/2 (15 + 25) = 1/2 (40) = 20 meters per second.The distance traveled = (average speed) x (time) = (20 x 7) = 140 meters.

At 25 meters per second a car will travel 100 meters in 4 seconds and 1000 meters in 40 seconds.
It will take 3.3 seconds to travel 44 meters at 48kph.
Acceleration is zero velocity is constant at 8m every second acceleration is the gradient of velocity and the gadient of a constant = 0
