Scientists are preparing two satellites to be launched. The satellite, Space Explorer A, flies 42000 miles in 15 hours. The table below represents the number of miles, yy, that the satellite, Space Explorer B, flies in xx hours.

To find out how many miles per hour each satellite travels, we need to calculate the speed for both Space Explorer A and Space Explorer B.

For Space Explorer A:

The satellite travels 42,000 miles in 15 hours.

Speed (miles per hour) = Total miles / Total hours
= 42,000 miles / 15 hours
= 2,800 miles per hour.

For Space Explorer B:

From the data provided, we can calculate the speed for Space Explorer B for each duration given in the table:

1. For x = 22 hours, y = 1,5200 miles: Speed = 1,5200 miles / 22 hours = 700 miles per hour.

2. For x = 44 hours, y = 3,0400 miles: Speed = 3,0400 miles / 44 hours = 690 miles per hour.

3. For x = 66 hours, y = 4,5600 miles: Speed = 4,5600 miles / 66 hours = 690 miles per hour.

4. For x = 88 hours, y = 6,0800 miles: Speed = 6,0800 miles / 88 hours = 690 miles per hour.

The average speed for Space Explorer B from all these values shows that it consistently travels around 690 miles per hour.

Now, comparing the two:

Space Explorer A travels: 2,800 miles per hour

Space Explorer B travels: Approximately 690 miles per hour.

Therefore,

Space Explorer A travels more miles per hour than Space Explorer B.
