Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How fast does a meteor travel?
A
Faster than a Cheetah
B
Very, very, very slow
C
11.2-72.2 km. per second
D
50-80 mph
Explanation: 

Detailed explanation-1: -Meteoroids enter Earth’s atmosphere at speeds typically of 12-40 km/s relative to the Earth. That is equivalent to going from New York to Los Angeles in 1.6 to 5.5 minutes.

Detailed explanation-2: -Scientists calculate that it was blasted into Earth by a 10-kilometer-wide asteroid or comet traveling 30 kilometers per second–150 times faster than a jet airliner.

Detailed explanation-3: -Since you know how fast the meteor is traveling (100 times 1/5 mile/second), you can use time = distance/velocity to calculate how long it will take for the meteor to reach the Earth.

Detailed explanation-4: -The meteoroid entered at a record speed of 64, 000 ± 1, 600 mph (28.6 ± 0.7 km/s), the fastest fireball on record from which meteorites were later recovered. It broke apart at an altitude of 157, 000 ft (48 km), the highest breakup event on record resulting in meteorites on the ground.
