Chen bikes 212 miles in 512 hour. What is Chen’s unit rate in miles per hour

Unit rate = 0.414 mph

Step-by-step explanation:

Distance travelled = 212 miles

Time taken = 512 hours

53/128 mph

Step-by-step explanation:

Unit rate is essentially just asking for the number of miles Chen can bike in only 1 hour. That's what "unit" means - 1.

Here, we know that Chen can bike 212 miles in 512 hours, so let's set up a proportion:

, where x is the number of miles Chen can bike in 1 hour

Cross multiply:

512x = 212

Divide by 512:

x = 212 / 512 = 53/128 miles

So, Chen's unit rate is 53/128 mph.

the graph on the bottom right

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
