Answer: Sample answer : a model is an estimate or approximation of a data set. In the real world, there are too many variables to know exactly what will happen. However, if a model is a good fit, then it can be used to make predictions about what will happen. With a useful model, a predicted value should be a good estimate of an observed value.

Basically meaning that no model can exactly be on point with whatever it is modeling. Two things cannot be EXACTLY identical to what they are referring to, but it is saying that some can get close enough to be useful as an example.

An ant crawls at a rate of 216 ft per minute.
AysviL [449]
First, we need to understand the speed formula:

The time used = distance ÷ rate

In this case, the time needed would be:

5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6

When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:

=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)

Factorize 26 and 13,we get:

=2/5 x 6/1
= 12/5 ft or 2.4 ft

Therefore the answer is 12/5ft or 2.4ft.

Hope it helps!
