First of all, you must find out how many miles it takes to go 4 hours and 8 hours.
112 ÷ 4 = 28 miles per hour
112 ÷ 8 = 14 miles per hour
So, going downstream will take 28 miles per hour and going in still water will take 14 miles per hour.
5280 ft =1 mi
hour =3600seconds 5280/3 =1760 yd= 1 mi
5yd/sec=x/3600
x=18000 yd/1760yd
x=10.227 miles
Answer:
x=72
Step-by-step explanation:
Multiply both sides by 9 (x=8 times 9)
x
- = 8
9
Let x = 72
72
_ =8
9
8=8
Therefore x =72
0.2, 0.3, 0.4, 0.5 if 0 doesnt count then exclude 0.2.
-0.2 + 0.2 = 0
-0.2 + 0.3 = 0.1
-0.2 + 0.4 = 0.2
-0.2 + 0.5 = 0.3
