36 km = 1 hour
198=x
x=198/36

jim_thompson5910 · Answer

$$\Large \text{distance} = \text{speed} * \text{time}$$

divide both sides by "speed" to solve for "time"

$$\Large \text{time} = \frac{\text{distance}}{\text{speed}}$$

speed is r if you are confused

Iknow the answer would be 5.5 but not sure if it is c or d

jim_thompson5910 · Answer

yes, r = rate = speed

rate and speed are interchangeable

xapproachesinfinity · Answer

well r was km/h
so it has to be hours

xapproachesinfinity · Answer

km cancels

xapproachesinfinity · Answer

you have km/km/h
so km disappears leaving only h

anonymous · Answer

So the answer would be d

xapproachesinfinity · Answer

and at any rate, time is never km
it always something that indicates time like seconds , min , hours
