EXTREMELY URGENT Algebra 1 Question

Question

Steven needs to unload a truck containing boxes filled with video consoles. He wants to determine the time required to unload the truck.

Which quantity will help Steven to determine the time required?

A. The number of boxes in the truck

B. The number of boxes in the truck and the weight of each box

C. The time it took to unload a box

D. The time taken to unload the box and the number of boxes in the truck

I choose D but am not sure if it is correct.

Answer 1

You are correct. D is the correct answer here.

In order to know how much time is required to unload a truck with b number of boxes, you need to know how long it takes to unload one box. If one box takes 1 minute to unload, then 60 boxes will take 60 minutes to unload.

T = total time to unload the truck

b = number of boxes

t = time to unload each box

T = (b)(t)
