QUESTION:

An object travels 16m in 5s and then another 16m in 3s. What is the average speed of the object

TO FIND:

$\boxed{\blue{AVERAGE\:SPEED}}$

FORMULA:

$Average\:speed=\frac {Distance}{Speed}$

SOLUTION:

$Average\:Speed=\frac {16\:m+16\:m}{5\:sec+3\:sec}$

$Average\:Speed=\frac {32\:m}{8\:sec}$

$Average\:Speed=4\:m\:per\:sec$

Answer 2

The average speed of the object is 4 m/s.

Given,

Distance, d1=16 m

Time for covering 16 m, t1=5 seconds

Distance, d2=16 m

Time for covering 16 m, t2=3 seconds.

To find,

the average speed of the object.

Solution:

Average speed is equal to the ratio of total distance travelled and total time taken.

Average speed=total distance covered/total time taken

Average speed=(d1+d2)/(t1+t2)

Average speed=(16+16)/(5+3)

Average speed=32/8

Average speed=4 m/s.
