Answer:
If you're looking for an answer in m/s then 8.33.. ms^-1
Explanation:
To determine average speed then we simply need to divide the total distance travelled by the total time it took to travel that distance.
I.e. 250/30=8.33m/s
To convert this to km/h we simply need to multiply the answer in m/s by 3.6 which gives us approximately 30km/h
