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
