Answer 2

Answer:

Here we have,

Distance from point A to B = 300 m

Time taken = 2 minute 30 second = 2 x 60 + 30 s = 150 s

Distance from point B to C = 100 m

Time taken = 1 minute = 60 s

(a)  Average speed and velocity from point A to B

2 ms -1   east  

(b)  Average speed and velocity from B to C

166 ms -1  west
