Answer:

B. d(t) = 9t; 23.22 ft

Explanation:

m= minutes

2.58*m

2.58*9=23.22

The snail will travel 23.32 feet in 9 minutes.

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 .

2.58m

So, in m you write the minutes.

2.58*9=23.22 feet per minute
