Question

Juan and Kinsley volunteer to send texts reminding people to vote in an election. Juan sends 80 texts in 40 minutes. Kinsley sends 90 texts in 30 minutes. How many texts does Juan send each minute?

Answer 1

Juan sends 120 texts per minute

Kinsley sends 180 texts per minute

Explanation:

to figure out the number of texts per minute we can set up proportions:

Juan: 80 texts in 40 minutes is equal to 't' number of texts in 60 minutes

`(80)/(40)` =
`(t)/(60)`

we can solve proportions by cross-multiplying but we can make things easier by simplifying 80/40 to 2/1 first

`(2)/(1)` =
`(t)/(60)`

t = 120

Therefore, Juan sends 120 texts per minute

Kinsley: 90 texts in 30 minutes is equal to 't' number of texts in 60 minutes

`(3)/(1)` =
`(t)/(60)`

t = 180

Therefore, Kinsley sends 180 texts per minute
