Question

use the unit rate to find the number of cranes adriana can fold in 45 minutes.
cranes \tminutes
2 \t1
50 \t25
\t45

Explanation:

Step1: Identify the unit rate

From the table, in 1 minute, Adriana can fold 2 cranes. So the unit rate is 2 cranes per minute.

Step2: Calculate cranes in 45 minutes

To find the number of cranes in 45 minutes, we multiply the unit rate by 45 minutes. Let \( n \) be the number of cranes. Then \( n = 2\times45 \).
\( n = 90 \)

Answer:

90
