Answer 1

• 533 1/3 m, 900 m, 4 1/8 laps

Explanation:

• A telesecundaria school has a race track that is 3/5 of a kilometer long. Three students ran the following distances: Juanita 1 1/3 laps, Esperanza 2 1/4 laps and Evelyn: 1650 m, how many meters did Juanita and Esperanza run? And how many laps did Evelyn turn?

---------------------------

1 lap = 400 m

Juanita ran:

• 1 1/3 laps = 4/3 laps = 4/3*400 m = 1600/3 m= 533 1/3 m

Esperanza ran:

• 2 1/4 laps = 9/4 laps = 9/4*400 m = 900 m

Evelyn ran:

• 1650 m = 1650 *1/400 = 4 50/400 laps = 4 1/8 laps
