A plane flew at a constant speed between Denver and Chicago. It took the plane 1.5 hours to fly 915 miles.
How far would the plane fly in t hours at this speed?

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

for future students the answer is b

hope i
