Negative acceleration
Acceleration is the change in velocity divided by the time it takes to make that change;a= delta v/delta tAs you can see, the change in velocity for both vehicles is the same (10km/h), and the question states that they do it in the same amount of time. So the acceleration is the same;delta v1/delta t1 = delta v2/delta t2 = a.The fact that the motorcycle is already at a much higher speed is irrelevant.
Since the direction of motion is not given, nor implied by speed, the acceleration can have any value between 0.146 ms-2 and 0.0625 ms-2.
10 meters/second2 refers to an acceleration. It is the same as 10 (meters/second) / second, and means that every second, the speed changes by 10 meters/second.
Gravity doesn't have speed , it has acceleration. On Earth gravitational acceleration is 9.8 ms^-2. Often approximated to 10 ms^-2
if your speed is in the positive direction you are slowing down and acceleration is the opposite direction and is negative acceleration.However if your speed is the negative direction ( like running backwards) and you slow down then acceleration is in the opposite direction and positive.In your case if speed is 10 kmh positive going to 6kmh then acceleration is negative
Negative acceleration

The top speed of the A-10 is about 706 kmh or 439 mph
smart
Acceleration = (change in speed) / (time for the change)= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2The acceleration is negative, which is a description of slowing down.
Acceleration = (change in speed) / (change in time) = (30 m/s) / (10 sec) = 3 meters per second2
3 hours and 10 minutes!
Since the direction of motion is not given, nor implied by speed, the acceleration can have any value between 0.146 ms-2 and 0.0625 ms-2.
if its km/h then it describes your speed in kilometers per hour
The car is travelling fast. However, its acceleation is zero because there is no change in velocity in 10 s.
