For this case we have that by definition of properties logarithm is met:

So, rewriting the expression we have:

By definition of logarithm we have to:
is equivalent to
So:

ANswer:

So, you basically plug the values into the formula you have been given. D divided by T gives you the average speed.
We know the distance D is 145 miles and the Time T is 2.5 hours.
So, 145/2.5=58
Therefore, the cars average speed was 58 miles / hour
