Answer:
1. 3 minutes
2. 27 inches
3. The snails moves at 3 inches per minute
Step-by-step explanation:
1. We know that the equation gives d = 3t gives us the distance travelled (in inches) in time t ( in minutes).
Now, how many minutes does it take the snail to travel 9 inches? The answer is given by putting d = 9 into the above equation.

dividing both sides by 3 gives


Therefore, it takes the snail 3 minutes to cover 9 inches.
2. To find out, we put t = 9 into the above equation gives


Hence, the snail travels 27 inches in 9 minutes.
3. In the equation d = 3t what does 3 mean?
The fomula d = 3t is a distance formula d = vt with v = 3.
Since in the distance formula v = speed, we conclude that 3 in the equation represents the speed of the snail.
which means that the 3 is the speed of the snail.
