At a football stadium it takes 1 hour for the spectators to get in if 6 gates are used. How long will it take them to get in of 3 gates are opened. Solve this problem by numbers maths problem

If it takes 1 hour for the spectators to get in with 6 gates open, then we can write:

Time for 1 gate to open = 6 hours

Now, if we only have 3 gates open, we can use the formula:

Time = (Number of gates) x (Time for 1 gate to open)

Time = 3 x 6

Time = 18

Therefore, it would take the spectators 18 hours to get in if only 3 gates are open.

To solve this problem using numbers, we can use the concept of "man-hour," which represents the work done by one person in one hour.

Given that it takes 1 hour for spectators to get in when 6 gates are used, this means that each gate allows spectators to enter in 1/6th of an hour.

So, let's calculate the total number of man-hours needed to get all the spectators inside the stadium when 6 gates are opened:

Total man-hours = 1 hour per gate * 6 gates = 6 man-hours

Now, we are asked to find out how long it will take if only 3 gates are opened. Let's calculate the time in hours:

Time = Total man-hours / Number of gates
Time = 6 man-hours / 3 gates = 2 hours

Therefore, it will take 2 hours for the spectators to get in if only 3 gates are opened.
