Vikentia [17]

Answer:

See Below

Step-by-step explanation:

1) 180 ft / 6 sec

To find a unit rate, you need to have a denominator of 1 and to to do that, you can divide the numerator and denominator by the same number, in this case: 6.

30 ft / 1 sec

2) 86 mi / 5 hr

Same as above^(except dividing by 5)

17.2 mi / 1 hr

3) 83 mi / 5 hr

Same as above^^

16.6 mi / 1 hr

We can rewrite this as: 16.6 mph

4) 93 mi / 5 hr

Same as above^^^

18.6 mi / 1 hr

5) 150 mi / 4 hr

Same as above^^^^

37.5 mi / 1 hr

How do I find the variable?<br><br> N x 1/5 = 2/15<br><br> N / 1/5 = 1/3
algol [13]
First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15

N=2/15
