Suppose q was the midpoint of pr. use the information to find its missing value
• pq equals 3x +14 and qr equals 7x -10; find x
• pq equals 2x +1 and qr equals 5x -44; find pq
• pq equals 6x +25 and qr equals 16 minus 3x; find pr
• pr equals 6x +31 and qr equals 483; find x

Answer :-

13) x = 6

14) PQ = 31

15 ) PR = 38

16 ) x = 13

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
