Question

answer from question 2 plz!

Answer 1

♠Answer♠

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

Answer 2

Hello Dear !
_____________________________________________________________
2)when an object start travelling from point A to B then B to C 
in which in two intervals t1=t2 = t 
and V1 for AB and V2 for BC
actually in this case distance AC = Displacement AC 
So Av velocity comes to equal Av Speed
_____________________________________________________________
Average speed = average velocity = v1t+v2t/2
                                                       = v1 + v2 /2
_____________________________________________________________
3)Odometer measures the distance 

4) In uniform motion path of object is like straight line 

5) Here ,
   speed(v) = 3X 10 ^8 
   time   (t)  = 60 X 5  = 300 seconds 
   distance  =  300 X 3 X 10 ^ 8 m 
                   =  3 X 3 X 10 ^10  m
                   =   9 X 10 ^10 m
