Rewrite the fractions as improper fractions:
1. −4 2/5 ÷ (−5)
= -22/5 ÷ −5/1
= -22/5 x -1/5
=22/25
2. −4 4/5÷4
= -24/5 ÷ 4/1
= -24/5 x 1/4
= -6/5
= -1 1/5
3. −2 1/8 ÷ 1 1/4
= -17/8 ÷ 5/4
= -17/8 x 4/5
= -68/40
= -17/10
=-1 7/10
4. −6 7/8 ÷ (−3 3/4)
= -55/8 ÷ -15/4
= -55/8 x -4/15
= 220/40
= 11/6
= 1 5/6
5. −8 3/4÷ 2 1/6
= -35/4 ÷ 13/6
= -35/4 x 6/13
= -210/52
= - 105/26
= -4 1/26
Answer:
V = 160mph
Step-by-step explanation:
We need to start from the formula of speed: V=d/t
We have two travels, with and against the wind, both done in the same time.
Clearing t from the formula, we will have: t=d/V2
450miles/V-35mph (speed of the wind is subtracted)
702miles/V+35mph (speed of the wind is subtracted)
Now, we find V:
450miles/V-35mph = 702miles/V+35
450*V+35 = 702*V-35
450V+15,750 = 702V-24,570
702V-450V = 15,750 + 24,570
252V = 40,320
V = 40,320/252
V = 160mph
