Question

an object moves 18 metre in the first 3 seconds
22 metres in the next 3 sec & 14 metres in the last 3 seconds
what is its average speed?​

Answer 1

✫ 18m/3s = 6m/s

✫ 22m/3s = 7.33m/s

✫ 14m/3s = 4.66m/s

☞Average of all three speeds

(6m/s + 7.3m/s + 4.6m/s)/3

= (17.99m/s)/3

= 5.9966666666666m/s

≅ 6m/s
