Question 1166228
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.
