Answer:

[tex]Speed = 219.81\ miles/hour[/tex]

Step-by-step explanation:

Given

[tex]Speed = 219.809\ miles/hour[/tex]

Solving (a) Approximate to nearest hundredth

[tex]Speed = 219.809\ miles/hour[/tex]

[tex]Speed = 219.81\ miles/hour[/tex] -- Approximated

See (b) for explanation

Solving (b): Steps for (a)

First, we need to note the digit in the thousandth place value

[tex]Digit = 9[/tex]

Since:

[tex]9\geq 5[/tex]

We have to increase the digit in the hundredth position by 1

This gives:

[tex]Speed = 219.81\ miles/hour[/tex]

Hence:

Option B answers the question
