1. A motorboat travels 196 meters in 20 seconds. What is the motorboat's unit rate of speed? Step1. Write equivalent ratios.
The boat's rate of speed is 196m/20 secs.
Let X represent the unknown. The second ratio is: xM/1 sec.

Step2. set up and solve a proportion.

19/20 = X/1

196 . = 20 .
=
X =

The unit rate meters per second.
