The time t required to drive a certain distance varies inversely with the speed r. if it takes 2 hours to drive the distance at 67 miles per hour, how long will it take to drive the same distance at 55 miles per hour? a. about 1.64 hours b. about 134 hours c. about 2.45 hours d. about 61 hours

angle addition postulate

2x=56

step-by-step explanation:

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:
