Answer:
and
Step-by-step explanation:
Consider given system ,
We have to solve for and
In matrix form,
then this is in form of AX = b,
A=
X=
b=
Pre-multiply by both side, we get,
..............(1)
First finding inverse of A ,
Thus, inverse of A is ,
Now substitute in (1) , we get,
Multiply , we get,
Thus, and
5280 feet in a mile x 15 seconds = 79200 seconds to go 1 mile
79200 seconds / 3600 (seconds in an hour) = 22 hours
It would take 22 hours for the insect to crawl a mile.
