CPM Homework Help : CC2MN Problem 4-61

In a recent snail race, the winning snail traveled $5.85$ cm in $\frac { 3 } { 4 }$ of a minute. How fast was the snail traveling in centimeters per second?

Step 1:

Convert three fourths of a minute to seconds, since the question asks for centimeters per second.

$\left(\frac{3}{4}\text{minute}\right)\left(60 \frac{\text{seconds}}{\text{minute}}\right)=45\text{ seconds}$

Step 2:

Divide the distance traveled by the time it took to complete the race.

$\frac{5.85}{45}=0.13$ centimeters per second

Answer:

$0.13$ centimeters per second
