14 Select the correct answer. Triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″. If vertex P is at (3, -4) and vertex Q is at (5, -1), what are the coordinates of vertices P″ and Q″? A. P″(4.5, -6) and Q″(7.5, 1.5) B. P″(4.5, -6) and Q″(7.5, -1.5) C. P″(-9, 12) and Q″(15, -3) D. P″(9, -12) and Q″(15, -3) E. P"(-9, -12) and Q"(-15, -3)

hope this : )

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
