A dump truck weighs 11.25 tons when empty. A conveyor belt pours sand into the truck at a constant rate of 14 ton per minute until it is full.

Let t represent the elapsed time in minutes. Let w represent the weight of the truck after t minutes.

Write an equation for w in terms of t.

For this case, the first thing we must do is define variables.

We have then:

t: time in minutes

The linear equation that represents the

problem is given by: w (t) = (1/4) t + 11.25

the square root of what number? if you add that, then someone will probably answer the question.

the bolded word " farsighted" could be replaced with visionary.
