Question

510 visitors in 30 hours or 960 visitors in 60 hours, which is greater​

Answer 1

The 30 hours is greater.

Explanation:

For the 30 hours :
`(510 visitors)/(30 hours) = (17 visitors)/(hour)`

For the 60 hours :
`(960 visitors)/(60 hours) = (16 visitors)/(hour)`

Thus the 30 hours is greater.

Answer 2

510 in 30 because that would be 17 per hour and 960 in 60 would be 16 per hour
