Question

A radar isn’t designed to report the track of an aircraft every second . If this radar reports 30 tracks in one minute , what percentage of the time did the radar track the aircraft

Answer 1

60 seconds in a minute 30/60 is .5 so 50%

Answer 2

We know that one minute is equivalent to 60 seconds.
The given radar t=reports 30 tracks in 60 seconds (one minute).

To get the percentage of time in which the radar track the aircraft, we will divide the number of tracks reported by the total time and then multiply the quotient by 100 to get the percentage as follows:
% of time = (30/60) * 100
                = (0.5) * 100
                = 50%
