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
Answer:
The approximated value of JK is 10.6 cm answer (A)
Step-by-step explanation:
∵ JI // KH // LG
∵ XI and XJ are two transversal
∴ 
∵ LK = 18 cm , GH = 22 cm and HI = 13 cm
∴ 
∴ KJ = (13)(18) ÷ 22 = 10.6363 cm
∴ The approximated value of JK is 10.6 cm
