21 vueltas y Evelyn: 1650 m. ¿Cuántos metros corrieron Juanita y Esperanza?
¿Y cuántas vueltas dio Evelyn?
Answer:
Juanita and Esperanza run 400 meters and 8400 meters respectively and Evelyn make 4.125 laps.
Step-by-step explanation:
The complete question is: A telesecundaria school has a race track that measures one kilometer.
Three students ran the following distances Juanita: 1 laps, Esperanza 21 laps and Evelyn: 1650 m. How many meters did Juanita and Esperanza run? And how many laps did Evelyn make?
As we know that 1 meter = 0.0025 laps
So, the number of laps Evelyn make = 1650 0.0025
= 4.125 laps
Also, 1 lap = meters
1 lap = 400 meters
So, the meters that Juanita run = 1 400 = 400 meters
Similarly, the meters that Esperanza run = 21 400
= 8400 meters
Hence, Juanita and Esperanza run 400 meters and 8400 meters respectively and Evelyn make 4.125 laps.
Juanita ran 1 kilometer and Esperanza ran 21 kilometers. Evelyn ran 1 lap.
To find out how many meters Juanita and Esperanza ran, we need to add up their distances. Juanita ran 1 lap, which is equal to the length of the track. Since the track is 1 kilometer long, Juanita ran 1 kilometer. Esperanza ran 21 laps, so she ran 21 kilometers.
Evelyn ran 1650 meters. To find out how many laps Evelyn ran, we need to divide 1650 by the length of the track. Since the track is 1 kilometer long, Evelyn ran either 1 lap or 1.65 laps. However, we're told that Evelyn ran 1650 meters, so she ran 1 lap.
