Aspace plane skims the edge of space at 4000 miles per hour. neglecting altitude, if the circumference of the planet is approximately 25000 miles, how long will it take for the plane to travel around the planet?

6 hour 20 minutes

Step-by-step explanation:

We are given that a space plane skims  the edge of space at 400 miles per hour.

Circumference of the planet=25000 miles approximately

We have to find the time taken by the plane to travel around the planet.

Speed of plane=4000 miles per hour

Total distance traveled by the plane= approximately 25000 miles

Because plane travel in circular path therefore, distance

traveled by plane=Circumference of planet

Time =

Substitute the values then we get

Time =

Time=

1 hour=60 minutes

Hence, the plane takes time to travel around the planet=6 hour 20 minutes

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

r = 78539458390583095803458309458039485093485 or just 3
