Acyclist rides his bike at a rate 15 of kilometers per hour. what is this rate in kilometers per minute? how many kilometers will the cyclist travel in 10 minutes? do not round your answers.

a. 15km/hr= 0.25km/min

b. 0.04166666666km in 10minutes

Step-by-step explanation:

a. 15km/hr to km/min= 1 hour is 60 minutes

so 15km/60mins = 0.25km/min

b. every 1 hour(60mins) the cyclist travels a distance of 15km

in 10 mins he travels;

from a. we have 15km/hr to be 0.25km/min so we use this value

0.25 = 60mins

x = 10 mins

x = (10 *0.25)/60 = 0.04166666666km

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
