Question

Last week Bryan traveled 4 miles by a bus, 18 miles by a train, 11 miles by a van, 33 miles by a car, 7 miles by a bike and walked 2 miles.

What is the range in miles for the different ways that Bryan traveled?

FOUND ANSWER: 31

Answer 1

31

Explanation:

31

The range is the difference between the largest and smallest number.

range = biggest − smallest = 33 − 2 = 31

Answer 2

`\boxed{\text{[2, 33]}}`

Explanation:

The range is the spread of the y-values (minimum to maximum distance travelled).

The minimum is 2 mi, and the maximum is 33 mi, so the range is from 2 to 33.

In interval notation, the range is
`\boxed{\textbf{[2, 33]}}`
