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
1. 2 2/3

2. 9/5*7/3 9*7=63 5*3=15 so 63/15=21/5=4 1/5=4.2
The ? Is 3
As 4^3 = 64
4x4x4= 64
