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 =[tex]\frac{distance}{speed}[/tex]
Substitute the values then we get
Time =[tex]\frac{25000}{4000}=\frac{25}{4}=6\frac{1}{4} hours[/tex]
Time=[tex]6 hour +\frac{1}{4}\times 60 minutes= 6\;hour\;20 minutes[/tex]
1 hour=60 minutes
Hence, the plane takes time to travel around the planet=6 hour 20 minutes
