(10 - 5 2/3) * -2 + x = 8 2/3
(9 3/3 - 5 2/3) * -2 + x = 8 2/3
4 1/3 * -2 + x = 26/3
13/3 * -2 + x = 26/3
-26/3 + x = 26/3
x = 26/3 + 26/3
x = 52/3 or 17 1/3 <==
Answer:
a and c
Step-by-step explanation:
Answer:
T1 = 975 / (205 + V) flying with wind
T2 = 975 / (205 - V) flying against wind
T2 = T1 + 2
975 * {1 / (205 - V) - 1 / (205 + V)] = 2
(205 + V + V -205) / (205^2 - V^2) = 2 / 975
V^2 + 975 V - 42025 = 0 rearranging
V = 41.3
Values of flying are 246.3 and 163.7
Check:
T1 = 975 / 246.3 = 3.96 hrs
T2 = 975 / 163.7 = 5.96 hrs
