Answer:

Ms. Thomas was driving at constant rate of 52 miles/hour.

Step-by-step explanation:

Given:

Total time to travel (t) = 45 minutes

Distance drove (d) = 39 miles

we need to find the constant rate in miles per hour at which she was driving.

Solution:

Now we know that;

We need to find constant rate at miles per hour;

But time is given in minutes.

So we will convert minutes into hour by dividing by 60 we get;

time t =\frac{45}{60}= 0.75\ hrs

Now we know that;

Distance is equal to rate times time.

framing in equation form we get;

distance d =rt

Or

rate r= \frac{d}{t} = \frac{39}{0.75}= 52 \ mi/hr

Hence Ms. Thomas was driving at constant rate of 52 miles/hour.
