Question

Dan tested three cameras last weekend write the numbers of pictures taken per second for each camera then determine which camera took the pictures the fastest the first camera took 54 pictures and 9 seconds the second camera took 20 pictures and 5 seconds and the third camera took 21 pictures in 7 seconds

Answer 1

To find the number of pictures taken per second for each camera, we divide the total number of pictures taken by the total time taken:

For the first camera: 54 pictures / 9 seconds = 6 pictures/second
For the second camera: 20 pictures / 5 seconds = 4 pictures/second
For the third camera: 21 pictures / 7 seconds = 3 pictures/second

From these calculations, we can determine that the first camera took the pictures the fastest, at a rate of 6 pictures per second.
