The time it takes to travel a fixed distance varies inversely with the speed traveled. if it takes pam 40 minutes to bike to her fishing spot at 9 miles per hour, how long will it take her if she rides at 12 miles per hour ?

Hi there,  Welcome to  I see this is your first posted question, Even though I am no expert I will try to answer your question.

Step-by-step explanation:

In order to solve this problem, you need to apply the formula y = k/x. Where y is the time it takes and x is how fast she is driving.

Substitute our given information to the formula to find k,  we have :  40 = k/9. --> k = (40).9 = 360

Then do the same thing in the new number using the found k to find the time :  y = 360/ 12= 30 s

It takes 30s if she rides at 12 m/h

Hope this help

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
