Question

two ships traveling from dumaguete to cagayan de oro differ in average speed by 10kph. the slower ship takes 3 hours longer to travel a 240-kilometer route than for the faster ship to travel a 200 kilometers route. find the speed of the slower ship

Answer 1

Explanation:

x = slower speed

(x+10) = faster speed

distance / rate = time

240 / (x) = 200 / (x+10) + 3 solve for 'x' ( using quadratic formula) to find : x = 30 km/hr and the faster ship is 40 km/hr
