Question

An object moves 18 m in the first 3 s , 22 m in the next 3 s and 14 m in the last 3 s. What is its average speed ?​

Answer 1

Explanation:

Average speed = Total distance/ Total time

= 18+22+14/ 3+3+3

= 54/9

= 6m/s

Answer 2

Answer:

Kinematics

Explanation:

★ Given ;

» Distance ( S1 ) = 18 m , Time ( t1 ) = 3 sec.

» Distance ( S2 ) = 22 m , Time ( t2 ) = 3 sec.

» Distance ( S3 ) = 14 m , Time ( t3 ) = 3 sec.

______________________________________________________________________________

★ Average Speed ( V ) = Total distance travelled / Total Time Taken

= S1 + S2 + S3 / T1 + T2 + T3

= 18 + 22 + 14 / 3 + 3 + 3

= 54 / 9

★ Average Speed ( V ) = 6 m / s ★
