Question

Suppose a crew member at an unloading dock can unload 3 trucks per hour and have already unloaded 17 trucks. Which equation can be used to medel the number of trucks the crew unloads after h hours?

A. 3h+17
B. 3h=17
C. 17h-3
D. 17h+3

Answer 1

A

Explanation:

3 trucks per hour and you have already unloaded 17

Answer 2

A. 3h+17

Explanation:

Given,

The initial number of unloaded trucks = 17,

Also, 3 trucks per hour can be uploaded,

So, the additional number of uploaded truck after h hours = 3h,

Hence, the total number of uploaded trucks after h hours = Initial uploaded trucks + additional trucks

= 17 + 3h

Which is the required equation,

Option A is correct.
