Question

At track practice, Coach Wilson told the team to split into groups of four for a special relay. The first runner had to run 1 lap around the track (440 yards). The second runner had to run 2 laps around the track. The third runner had to to run 3 laps around the track. The final runner had to run 4 laps around the track (1 mile). How many yards did each relay team team have to run altogether? *

Answer 1

You can multiply the number of laps each person ran by the yards in each lap and then add them together:

440 + 2(440) + 3(440) + 4(440)
= 440 + 880 + 1,320 + 1,760
= 4,440 yards

Or you can add the laps first, then multiply by the yards in each lap
(1 + 2 + 3 + 4)(440)
= 10 x 440
= 4,400 yards
