We know that ,
[tex]\bold{\longrightarrow \: speed = \frac{distance}{time}} \\ [/tex]
this formula can be transformed to find out distance , as follows ~
[tex]\bold {\: \longrightarrow \: distance = speed \times time}[/tex]
now ,
substituting the values in the formula stated above ,
[tex]\bold{\longrightarrow \: distance = 36 \times 6} \\ \\ \bold{\longrightarrow \: distance = 216 \: km}[/tex]
thus ,
the bus travels a distance of 216 km in 6 hours
hope helpful ~
