George found that he blinked 75 times in 10 minutes. At this rate how many minutes passed during 45 blinks?

Answer 1

First, let's determine the number of blinks George did in one minute (the unit rate). This can be done by write the rate 75 blinks in 10 minutes as :

75 blinks / 10 minutes = 7.5 Blinks/ 1 minute

Since 7.5 times 6 is equal to 45, the time needed for 45 blinks can be found by multiplying the unit rate by 6/6:

7.5/1 * 6/6 = 45 blinks in 6 minutes

Therefore, it would take 6 minutes to complete 45 blinks.
