A highway construction warning sign blinks on and off. In all, the sign is on for 0.88 of each minuite. For how many seconds is the sign on in 5 minutes?
60 * 0.88 = 52.8 seconds a minute
52.8 * 5 = ?
To find how many seconds the sign is on in 5 minutes, we need to multiply the number of seconds in 5 minutes by the fraction of time the sign is on.
There are 60 seconds in 1 minute, so in 5 minutes, there are 5 * 60 = 300 seconds.
The sign is on for 0.88 of each minute, which means it is on for 0.88 * 60 = 52.8 seconds in each minute.
Therefore, in 5 minutes, the sign is on for 52.8 * 5 = 264 seconds.
So, the sign is on for 264 seconds in 5 minutes.
