Answer:
b) 35.33 km/h
Step-by-step explanation:
1. Name the numbers given as follows:
distance: 212km
time: 6h
2. To obtain a unit rate for the situation of travelling 212 km in 6 hour, it is needed to divide the distance between the time, that is:
[tex]Unitrate=\frac{distance}{time}[/tex]
3. Replace the values in the equation to find the the unit rate and solve:
[tex]Unitrate=\frac{distance}{time}[/tex]
[tex]Unitrate=\frac{212km}{6h}[/tex]
[tex]Unitrate=35.33\frac{km}{h}[/tex]
