Chanita wants to swim the 21-mile English Channel in 48 hours. On the first day she swam 9 miles and then was picked up by a ferry to spend the night. The next day, she has 12 hours of daylight to complete the remaining distance. What inequality represents the minimum rate she has to swim on the second day to complete the distance?

Respuesta :

Answer:the minimum rate is 1 mile per hour.

Step-by-step explanation:

Chanita wants to swim the 21-mile English Channel in 48 hours. Total number of miles that she covered on the first day is 9 miles. Total distance left for her to cover would be

21 - 9 =12 miles.

The next day, she has 12 hours of daylight to complete the remaining distance. Let x represent the minimum rate she has to swim on the second day to complete the distance.

Speed = distance/time

Therefore,

x ≥ 12/12

x ≥ 1
