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 =
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

Answer:
Line LM
Step-by-step explanation:
First, we need to know what the slope is of a line that would be perpendicular to a line with a slope of -5/6. To find this, we take the reciprocal and multiply it by -1. Therefore, the line we are looking for needs to have a slope of 6/5.
Based on the fact that the slope is positive, we can eliminate lines PQ and JK as they have a negative slope. This leaves us with lines LM and NO.
To find out whether or not it is between LM and NO, you could eyeball it by looking at the graph and simply counting which might be faster if you understand how to do that (rise/run), or you can use the pair of coordinates given to you on each line to calculate for slope.
Line LM -
Line NO -
Based on this, we know that line LM is perpendicular to a line that has a slope of -5/6.
