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

$\Large \text{distance} = \text{speed} * \text{time}$ 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

6. jim_thompson5910

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

7. xapproachesinfinity

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

8. xapproachesinfinity

km cancels

9. xapproachesinfinity

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

So the answer would be d

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