d, the distance in miles
A.add 50
B.divide 50
C.multply 50

Answer 1

To find the distance \( d \) that Chloe drives after \( t \) hours, using the information that she drives at a constant speed of 50 miles per hour, you can use the formula for distance:

\[ d = \text{speed} \times \text{time} \]

In this case:

\[ d = 50 \times t \]

So, the correct choice from the options provided is:

C. multiply 50

This means that for any given value of \( t \) (the time in hours), you multiply it by 50 to get the distance \( d \) in miles.
