#### Explanation:

**information given**

*62 km driven in 2 h**driving same rate in 3 h*

**application**

*If Kevin drives 62 km in 2 h, then* *is his rate.*

**calculation**

*apply dimensional analysis with conversion factor*#(31\text(km))/(1\text(h))#

#3h\times(31\text( km))/(1\text( h))# *numerator's and denominator's units cancel out*

#3\cancel(\text(h))\times(31\text(km))/(1\cancel(\text(h)))# *multiply results*

#(3\times31\text(km))/1=(93\text(km))/1=93\text(km)# driven
