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
Answer:
$39
Step-by-step explanation:
$62 = t - $22 + $60 - $15
t = $39
Answer:
x=10
Step-by-step explanation:
The probability that you will not choose a blue marble is 28/45.
I found the table that accompanies this problem:
Time(h) 1 2 3 4 5
Distance (mi) 55 110 165 220 275
speed = distance / time
speed = 55/1 = 55 miles per hour
speed = 110/2 = 55 miles per hour
speed = 165/3 = 55 miles per hour
speed = 220/4 = 55 miles per hour
speed = 275/5 = 55 miles per hour
distance = speed * time
distance = 55 miles per hour * 6 hours
distance = 330 miles.
To get the distance traveled, simply multiply the speed by the number of hours spent travelling.
