It took Lin's dad about 3.6 miles for him to meet up with his family.
<h3>
Speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let d represent the distance travelled by Lin to meet up with his family. Hence:
Total time for Lin's Dad = d/0.24 + 5
Total time for Lin = d/0.18
Hence:
d/0.24 + 5 = d/0.18
100d/24 + 5 = 100d/18
1800d + 2160 = 2400d
d = 3.6 miles

Answer:
f(x) = x^2 -12x +20
Step-by-step explanation:
There are an infinite number of functions with zeros at those values of x. One simple polynomial function with those zeros is ...
f(x) = (x -10)(x -2) . . . . . each zero contributes a factor
f(x) = x^2 -12x +20
