Answer:
6 hours
Step-by-step explanation:
70 ÷ 4 = 17.5 ----- divide to find out how many miles she travels per hour.
Samantha is driving at 17.5 mph
105 ÷ 17.5 = 6 ----- divide to find out how long it will take to travel that distance.
distance ÷ time = speed
distance ÷ speed = time
Answer:
Step-by-step explanation:
Given: 
To find: value of x and y
Solution:
From equation (i) and (ii),
Put 
in (i)
11 pints equal 176 fluid ounces
Your numbers are all over the place, I will assume that you are saying that the slope is 13.
Looking at the formula for calculating slope/gradient, it is Rise/Run.
Rise/Run = y2 - y1 divided by x2 - x1. The reason for this is because if you minus one y value from the other y value you get the difference in values which is the rise, and if you minus one x value from the other x value you get the difference in value which is the run.
So by using this formula, you get:
(7 - 6) / (v - 9) = 13
Therefore 1/(v - 9) = 13
If you multiply both sides by (v-9), you get 1= 13v - 117
you rearrange it to 13v = 118
If you divide by 13, you get your answer = 9.0769
You can check your answer by putting this value back into the gradient formula.
(7-6)/(9.0769-9)
=13.004
