If a body covers equal distances in equal intervals of time, then its speed is uniform.
True
False
The average speed of a body is calculated by dividing the total distance travelled by the total time taken.
True
False
The distance travelled by a body is the speed of the body divided by the time taken.
True
False
If a car travels unequal distances in equal intervals of time, then its speed is uniform.
True
False
If distance is in metres (m) and time is in minutes (min), then speed is in m min-1.
