By how much does the speed of a vehicle moving in a straight line change each second when it is accelerating at 2 km/h·s? at 4 km/h·s? at 10 km/h·s? include all work, ! : )

Acceleration (A) = change in velocity (v) / time
A = (v2-v1) / time, when A = 2:
(v2-v1) = A×time = (2km/h•s)×1s = 2 km/h

when A = 4:
(v2-v1) = A×time = (4km/h•s)×1s = 4 km/h

when A = 10:
(v2-v1) = A×time = (10km/h•s)×1s = 10 km/h

English can you write this in english do we can you

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /
