Answer:
Step-by-step explanation:
This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:
Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):
and cross multiply to solve:
638x = 4466 so
x = 7 hrs

{0, 1, 2, 3, 4, .......}
All whole numbers excluding zero are the natural numbers.
{1, 2, 3, 4,........}
Irrational numbers are the part of real numbers written in the form of .
{}
