Question

A space 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?

Answer 1

Answer:

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 =$\frac{distance}{speed}$

Substitute the values then we get

Time =$\frac{25000}{4000}=\frac{25}{4}=6\frac{1}{4} hours$

Time=$6 hour +\frac{1}{4}\times 60 minutes= 6\;hour\;20 minutes$

1 hour=60 minutes

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