The complete statement is 16 times (5/2) equals 40.
A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
let, 16 times 'x' equals to 40.
Therefore, 16x = 40.
x = 40/16.
x = 20/8.
x = 10/4.
x = 5/2.

The mean distance Sarita ran for 5 days = 4.9 miles.
The mean of given data is the summation of all variables divided by the number of variables.
Mean = ∑X/n
where X represents variables and n represents the number of variables.
We have got data for 5 days. The variables are 5 miles, 4 miles, 5.5 miles, 4.5 miles, and 5.5 miles. Number of variables = 5.
∑X = 5 + 4 + 5.5 + 4.5 + 5.5 = 24.5 miles.
n = 5.
∴ Mean = ∑X/n = 24.5/5 = 4.9 miles.
The mean distance Sarita ran for 5 days = 4.9 miles.
