"A car is traveling at r speed. A plane is traveling at 5r speed. When will they both reach 200 miles?"

this is funny i came here to ask question but yet i'm answering them. the formula for this is S=D/T or Speed = Distance divided by time, but since you are looking for the time you need to get T by itself. To do so you have to multiply both sides by T then divide S from both sides. This will give you the equation T=D/S. Then just plug and chug as i like to say. Plug r into S of the equation then write another equation for the plane and plug 5r for S in that equation. The answers will be 200mi/r for the car and 40mi/r for the plane.
