Question

11. Una escuela telesecundaria tiene una pista de carreras que mide de kilómetro.

Answer 1

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 $\times$ 0.0025

                                                             = 4.125 laps

Also, 1 lap = $\frac{1}{0.0025}$ meters

        1 lap = 400 meters

So, the meters that Juanita run = 1 $\times$ 400 = 400 meters

Similarly, the meters that Esperanza run = 21 $\times$ 400

                                                                   = 8400 meters

Hence, Juanita and Esperanza run 400 meters and 8400 meters respectively and Evelyn make 4.125 laps.
