Question 1166228: two cars left left a gasoline station at the same time and headed in opposite directions how far each other will the cars be after 2.5 hours if their speed are 124 kph and 110 kph

since they're going in opposite directions, their kilometers are additive.

r * t = d
r is the rate
t is the time
d is the distance

at 124 kph, the formula for the first car becomes 124 * 2.5 = 310 kilometers.
at 110 kph, the formula for the second car becomes 110 * 2.5 = 275 kilometers.

both cars will be 310 + 275 = 585 kilometers from each other in 2.5 hours.
