5 a jet traveled 1875 miles in 5 hours.
find these rates:
a. miles per hour
375 420 mph

375 mph

b. miles per minute
7.75 mi/min
6.25 mi/min

c. minutes per mile
0.16 min/mi
0.22 min/mi

  a) 375 mph

  b) 6.25 mi/min

  c) 0.16 min/mi

Step-by-step explanation:

To find miles per hour, divide miles by hours:

a) (1875 mi)/(5 h) = 375 mi/h

__

b) You have hours in the denominator, and you want minutes there, so the conversion factor is (1 h)/(60 min):

  (375 mi/h)·(1 h)/(60 min) = (375/60) mi/min = 6.25 mi/min

__

c) Minutes per mile is the inverse of the value you just calculated:

  1/(6.25 mi/min) = (1/6.25) min/mi = 0.16 min/mi

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
