Answer :
Interpolation equation
Poit 1: (a,b)
Point 2: (c,d)
Intermediate point (x,y)
(d - b)/(c - a) = (y - b) / (x - a)
(a,b) = (2, 4.2)
(c,d) = (4, 5.6)
x = 3
(5.6 - 4.2) / (4 - 2) = (y - 4.2) / (3 -2)
y = [1.4/2]*[1] + 4.2
y = 0.7 + 4.2 = 4.9
Answer 4.9 miles
Poit 1: (a,b)
Point 2: (c,d)
Intermediate point (x,y)
(d - b)/(c - a) = (y - b) / (x - a)
(a,b) = (2, 4.2)
(c,d) = (4, 5.6)
x = 3
(5.6 - 4.2) / (4 - 2) = (y - 4.2) / (3 -2)
y = [1.4/2]*[1] + 4.2
y = 0.7 + 4.2 = 4.9
Answer 4.9 miles
Baded on the way that Heather has run a number of miles, we can say that the round off the answer to the nearest tenth of a mile is 4.6miles.
What is the expression about?
Notre that running is a from of exercise that can be done in different ways.
In the equation, there is:
Point 1: (a,b)
Point 2: (c,d)
Intermediate point (x,y)
(d - b)/(c - a) = (y - b) / (x - a)
(a,b) = (2, 4.2)
(c,d) = (4, 5.6)
x = 3
(5.6 - 4.2) / (4 - 2) = (y - 4.2) / (3 -2)
y = [1.4/2]*[1] + 4.2
y = 0.65+ 4.1 = 4.6
Therefore, the answer will be 4.6 miles
