An adult blinks about 450 times in 30 min. A 12 year old blinks about 150 times in 15 min. How many more times does an adult blink in 60 min. than a 12 year old?

Sagot :

150x2 because 15 minutes is half that of 30
=300
then times that by 2 again to get an hour so 600
then times 450 by 2 to get an hour so 900
then subtract 600 from 900 which is 300 
300 more times is your answer 

Answer:

300 times more.

Step-by-step explanation:

An adult blinks about in 30 minutes = 450 times

An adult blinks in one minute =  [tex]\frac{450}{30}[/tex]

                                                 = 15 times

In 60 minutes an adult blinks = 60 × 15 = 900 times

A 12 year old blinks about in 15 minutes = 150 times

A 12 year old blinks in one minute =  [tex]\frac{150}{15}[/tex]

                                                         = 10 times

In 60 minutes a 12 year old blinks = 60 × 10 = 600 times

The difference between the number of blinks in 60 minutes = 900 - 600

                                                                           = 300 times

In 60 minutes an adult blink 300 times more than a 12 year old.
