George found that he blinked 85 times in 15 minutes. At this rate, how many seconds passed during 51 blinks?

1 answer:

6 0

First convert the 15 minutes to seconds
60 sec-= 1 minute
900 sec = 15 minutes

ratio and proportion

85 blinks/900 sec= 51 blinks/ x seconds

cross multiply
85x=45900
divide by 85
x= 540 seconds
hope this helps

drek231 [11]

It is given in the problem that out of 25 students in Hansels class 17 students went to the class trip to the zoo. From the above information it is easy to find the percentage of students that went for the class trip to the zoo.
Total number of students in the class = 25
Number of students that went for the class trip to the zoo = 17
Then
Percentage of students that went to the zoo = (17/25) * 100
= (17 * 4) percent
= 68 percent
So 68% of the students in Hansels class went for the class trip to the zoo.
