Two ships travelling from Cebu to Samar differ in average speed by 10 kph. The slower ship takes 3 hours longer to travel a 240-kilometer route than for the faster ship to travel a 200-kilometer route. Find the speed of the slower ship.

Hint: Construct an equation t as the variable.

• the speed of the slower ship is 14.3 kilometers per hour

• the speed of the slower ship is 15.3 kilometers per hour

• the speed of the slower ship is 13.3 kilometers per hour

• the speed of the slower ship is 12.3 kilometers per hour
