At a furniture manufacturer, worker a can assemble a shelving unit in 5 hours. worker b can assemble the same shelving unit in 3 hours. which equation can be used to find t, the time it takes for worker a and worker b to assemble a shelving unit together?

We can use equation to solve for t.

Worker A and worker B takes t = 1.875 hours to assemble a shelving unit together.

Step-by-step explanation:

We have to find the equation that can be used to find t, the time it takes for worker A and worker B to assemble a shelving unit together.

So, Worker A and Worker B works at the rate of shelving unit per hour.

Given:  worker A can assemble a shelving unit in 5 hours.  

So, worker A works at a rate of   Hours to assemble a shelving

Also, given: Worker B can assemble the same shelving unit in 3 hours.

So, worker B works at a rate of   Hours to assemble a shelving.

Thus, equation becomes,

Solving we get,

LCM(3,5) = 15

Solve for t , we get,

Thus, worker A and worker B takes t = 1.875 hours to assemble a shelving unit together.

Thus, We can use equation to solve for t.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
