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

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
