Solution:
It should be noted:
- Given sentence: A motorboat travels 196 meters in 20 seconds.
Let's reread the sentence carefully.
A motorboat travels 196 meters in 20 seconds.
↥ ↥ ↥
196 meters = 20 seconds.
Equation formed: [tex]196 \space\ meters = 20 \space\ seconds[/tex]
To find the unit rate (meters/second), divide both sides by 20.
Divide both sides by 20.
- [tex]\frac{196}{20} \space\ meters = \frac{20}{20} \space\ seconds[/tex]
- => [tex]9.8 \space\ meters = 1 \space\ second[/tex]
Thus, the unit rate is 9.8 meters per second.
