Earth's diameter at the equator is about 7926 miles. A jet flies 550 miles per hour. How long would it take the jet to fly halfway around the equator?
the whole circumference is 7926π.
half the way around is 3963π.
since the plane goes 550 miles each hour, it will take
3963π/550 = 22.6 hours
To calculate how long it would take the jet to fly halfway around the equator, we need to find the distance it needs to cover.
The distance around the equator is the circumference of a circle, which can be calculated using the formula: C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the Earth at the equator is about 7926 miles, we can find the circumference:
C = π * 7926 miles
C ≈ 2π * 3963 miles
C ≈ 24,901 miles
So, the distance around the equator is approximately 24,901 miles.
To find the time it would take the jet to fly halfway around the equator, we divide this distance by the speed of the jet:
Time = Distance / Speed
Time = (24,901 miles / 2) / 550 miles per hour
Time ≈ 24,901 miles / 1100 miles per hour
Time ≈ 22.64 hours
Therefore, it would take approximately 22.64 hours for the jet to fly halfway around the equator.
To find out how long it would take the jet to fly halfway around the equator, we need to calculate the distance between the starting point and the halfway point on the equator.
The circumference of a circle, such as the Earth, can be calculated by multiplying its diameter by the mathematical constant π (pi). In this case, we will use the Earth's circumference at the equator, which is approximately 7926 miles.
To find the halfway point, we divide the circumference by 2:
7926 miles / 2 = 3963 miles
Now, we can calculate the time it would take for the jet to cover that distance.
The jet flies at a speed of 550 miles per hour. To find the time it takes to travel a certain distance, we divide the distance by the speed:
Time = Distance / Speed
Time = 3963 miles / 550 miles per hour ≈ 7.24 hours
Therefore, it would take the jet approximately 7.24 hours to fly halfway around the equator.
