Answer #1

speed is the rate of change in distance

average speed = the ratio of total distance travelled by the body to the total time taken to travel the distance

instantaneous speed is the speed of the body at any given instant of time.the for a body which is moving with uniform speed the average speed is equal to insantaneous speed.if the body is travelling with accelaration the instantaneous speed is different from average speed

in part A average speed is the instantaneous speed divided by total time. which is FALSE

part B)

vedtor : a physical quantity having both magnitude and directioni

scalar: a physical quantity having only magnitude and no direction

so A vector is a scalar with direction? TRUE
