Question

Ms Thomas drove at a constant rate for 45. She drove 39 miles during that time. If distance is determined by the equation d=rt where r is the constant rate in miles per hours what was ms Thomas constant rate?

Answer 1

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

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 =(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= (d)/(t) = (39)/(0.75)= 52 \ mi/hr`

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