Answer:
The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.
Step-by-step explanation:
Given that:
Distance traveled by jet against the wind = 2480 miles in 4 hours
Combined speed = =
Combined speed = 620 miles per hour
Distance traveled with wind = 7040 miles in 8 hours
Combined speed =
Combined speed = 880
Let,
Speed of jet = x
Speed of wind = y
When jet travels against the wind, the speed will be subtracted
x-y=620 Eqn 1
When jet travels with the wind, the speed will be added
x+y=880 Eqn 2
Adding Eqn 1 and 2
(x-y)+(x+y)=620+880
x-y+x+y=1500
2x=1500
Dividing both sides by 2
Putting x=750 in Eqn 2
750+y=880
y=880-750
y=130
Hence,
The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.
Answer:
A fair six-sized die is rolled. Find the probability of getting at least a 4.
There are 6 outcomes and three of them are 4, 5 or 6, so the probability of greater than or equal to 4 is 3/6=½.
