Luke: 1 practice 1 lap, 2 practices 2 laps, 3 practices 3 laps, 4 practices 4 laps

Alex: 1 practice 3 laps, 2 practices 6 laps, 3 practices 9 laps, 4 practices 12 laps

Luke ran 3 laps for 3 practices, and Alex ran 9 laps for 3 practices.

Answer:

Laps of Luke for 1,2,3 and 4 practices = 4

Laps of Alex for 1,2,3 and 4 practices = 12

For three practices Luke:Alex = 3:9

Step-by-step explanation:

Practice number             1            2            3             4

Luke (Laps)                      1            1             1              1

Alex  (Laps)                      3           3             3             3

Now by simply adding numbers of laps for Luke and Alex one can get the answer.

For Luke, total number of Laps = 1+1+1+1 = 4

For Alex, total number of Laps = 3+3+3+3 = 12

Now, for three practices

For Luke, total number of Laps = 1+1+1 = 3

For Alex, total number of Laps = 3+3+3 = 9

The comparison for three practices can be shown as

Luke:Alex = 3:9
