Final answer:
The rule 'multiply by 50' can be represented using the variable for time in hours, t, as the expression 50t.
Step-by-step explanation:
In this case, the rule 'multiply by 50' can be represented using the variable for time in hours, t, as the expression 50t. This means that if you multiply the time Jordyn has driven by 50, you will get the distance she has driven in miles. For example, if Jordyn has driven for 2 hours, the distance she has driven would be 50 × 2 = 100 miles.
