Acar and a motorcycle move in the same direction by the same highway. at the beginning, the distance between them is 105 km. the car driver maintains an average speed of 90 km/h. what is the average speed of the motorcyclist, if the car driver caught up with him in 3 hours?

the answer is 2/54

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
