Robert and Wilson got in trouble at football practice and have to run laps as a consequence. Robert, who runs at a rate of 1 lap per minute, had completed 4 laps already when he was joined on the track by Wilson, Wilson's pace is 5 laps per minute. At some point, the two will have run the same distance. How long will that take? How many laps will each boy have run?
If Robert runs at a pace of 1 Lap per minute, and had already finished 4 Laps when he was joined by Wilson on the field, who runs at a pace of 5 Laps per minute.
A minute later they would have both finished 5 Laps.
I hope that helped a bit?
