Answer:

Result = 0.0045

9 --------- 2 decimal place

5 --------- 2 decimal place

an adult blinks about 450 times in 30 minuets. a twelve year old blinks about 150 times in 15 minuets. how many more times does

Elena-2011 [213]

If an adult blinks 450 times in 30 minutes, then he will blink 900 times in 60 minutes.

A 12-year old blinks 150 times in 15 minutes, so he will blink (150 x 4) in 60 minutes, which comes out to: 600.

so 900-600

An adult blinks 300 times more in 60 minutes than a 12-year old.
