2) The magnitude of average velocity is equal to that of average speed when the distance travelled is equal to the displacement .
3)Odometer measures the distance travelled by the automobile
4) Straight line path
5)As we know , the distance travelled by radio wave ( signal) will be the product of the time it takes to travel and the speed it travels it with (Distance = speed × time ) here, distance will be :
3×10^8 × 300
9×10^10 metres
where 3×10^8 is the speed & 300 second is the time taken
