A system of equations is shown below. Which of the following replacements can be made to produce the same (xy) solution?
23-y=4
3r + 2y = 1
A Replace 2x - y = 4 with 8x - 4y = 4
B Replace 3x + 2y = 1 with 5x + y = 5.
Replace 3x + 2y = 1 with 6x + 2y = 2.
D Replace 2x - y = 4 with 3x + 2y = 1

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

you can use a^2+ b^2=c^2
