Answer: See explanation
Step-by-step explanation:
From the information, we are told that Mrs. Elizondo runs around a 400-meter track. If she runs 4 laps, the total meters will be:
= 400 × 4
= 1600 meters
Since she uses a constant speed of 250 meter per minute. The number if minutes taken to complete the 4 laps will be gotten by dividing 1600 by 250. This will be:
= 1600 / 250
= 6.4 minutes
= 6 minutes + (0.4 × 60 seconds).
= 6 minutes 24 seconds
