Question

A body travels 16 meters per 4 secs and then another 16 meters in 2 sec , what is the average seed of the body

Answer 1

it is given by total distance travelled by the moving object divided by total time taken to travel the total distance ( as Speed = Distance ÷ Time )

Now in the above case :-

Total Distance Covered = 16 + 16 = 32 m

Total Time Taken to Travel 32m = 4 + 2 = 6 s

Thus The Average Speed of the Moving Object = 32 ÷ 6 = 5.33 m/s

This is different from the Mathematical Average of Speeds

Speed of the object in first case = 16 ÷4 = 4 m / s

Speed of the object in second case = 16 ÷ 2 = 8 m / s .

Mathematical Average of Speeds = ( 4 + 8 ) ÷ 2 = 12 / 2 = 6 m / s .

Answer 2

Answer:

ans is 5.3m/sec formula to find average speed is total distance/total time taken so 16+16=32 which is distance and 4+2=6 which is time so divide them 32/6=5.3m/sec
