Let's assume that the total number of spectators is 600 (since we don't have any specific number in the problem).
If it takes one hour for the spectators to get in when 6 gates are used, then the number of spectators entering through each gate per hour is:
600/6 = 100 spectators per gate per hour
Now, if we open only 3 gates, the number of spectators entering through each gate per hour will increase to:
100 x 6/3 = 200 spectators per gate per hour
Therefore, it would take the spectators half an hour to get in when only 3 gates are opened:
600/200 = 3 hours
3 hours/2 = 1.5 hours = 90 minutes = 1 hour and 30 minutes
At a football stadium it takes one hour for the spectators to get in if 6 gates are used. How long will it take them to get in if 3 gates are opened.Maths problem solve this with numbers
