Question

Alejandro rides his bicycle to work. If he rides 10mph

Answer 1

Option B Inverse Variation because xy=240 is correct.

Step-by-step explanation:

if Alejandro rides 10 mph it takes him 24 minutes.

if Alejandro rides 12 mph it takes him 20 minutes.

Making table for given data set.

Considering miles as y and time as x

Miles(y)               Time (x)

10 mph             24 minutes

12 mph             20 minutes

If the miles are increasing the time taken is less, so the variation is inverse.

The formula used to find inverse variation is:

$y = \frac{k}{x}$

Where y is miles and x is time, and k is constant

Putting y = 10 and x = 24

$10 = \frac{k}{24} \\24*10= k\\240 = k$

So, the value of k constant is 240.

For any value of x and y the value of k will be 240

Hence Option B Inverse Variation because xy=240 is correct.
