Answer:
3.1567 * 10^-4 miles
Step-by-step explanation:
1 ft = 1.894 * 10^-4 miles , so
1 inch = 1.894 * 10^-4 / 12 miles
= 0.15783 * 10^-4
= 1.5783* 10^-5 miles ( in scientific form).
Multiplying this by 20 we get
31.567 * 10^-5
= 3.1567 * 10^-4 miles.
Answer:

x=2
Step-by-step explanation:
3x + 3y=-9
3x - 3y=21
-

3x-15=-9
x=2
13).
(600 ft / 5 min) x (1min / 60sec)
= (600 · 1 / 5 · 60) (ft · min / min · sec)
= 2 ft/sec
______________________________
14).
(120 yd / 2 min) x (3ft / 1yd) x (1min /60 sec)
= (120 · 3 · 1 / 2 · 1 · 60) (yd · ft · min / min · yd · sec)
= 3 ft/sec

15).
(60 mile /1 hour) x (5,280ft / 1mile) x (1hr / 3,600sec)
= (60 · 5,280 · 1 / 1 · 1 · 3,600) (mile · ft · hour / hour · mile · sec)
= 88 ft/sec .
