Question

An object travels 16m in 4s and 1 point
then another 16 m in 2s. What is
the average speed of the
object?
O a) 6 m/s
O b) 6.5 m/s
O c) 5.33 m/s
O d) 5 m/s​

Answer 1

Answer:

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:

5.33m/s

Explanation:

16+16=32,which is the total distance.

total time=4+2=6seconds

average speed=total distance/total time taken

= 32/6

= 5.33m/s
