Answer
As given
A snail travels at a rate of 2.58 feet per minute.
First write a rule to describe the function.
Let a is denoted the distance.
t is the time
Thus the function becomes
a = 2.58 × t
a = 2.58t
This denoted the distance travelled in t time.
Second how far will the snail travel in 9 minutes .
Put t = 9 mintues in the above equation.
a = 2.58 × 9
a = 23.22 feet
Therefore the distance travelled in 9 mintues are 23.22 feet .
