A dog barks 20 times in 10 minutes. Find the unit rate of barks per minute, then convert to barks per hour.

well to find it per mintue it would be 20 divided by ten which equals 2 barks per minute and to find it per hour it would be 60*2 which equals 120 barks per hour

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
