Answer:
1.33minutes
Step-by-step explanation:
We need to find the combined speed for all the boys
given
Brendan completes 1 lap in 4 minutes= 1/4 laps per minutes
Miguel completes 1 lap in 6 minutes=1/6 laps per minutes
Jeron completes 1 lap in 3 minutes= 1/3 laps per minutes
the the combined minutes be x
1/4+1/6+1/3= 1/x
3+2+4/12=1/x
9/12=1/x
3/4=1/x
x=4/3 minutes
x=1.33minute
Thus running together at the same rate it will take them 1.33minutes to complete a lap together
