Two ships

Two ships sailed from Venice - a cargo speed of 10 knots and a ferry speed of 18 knots. At what time will the ferry catch up with the cargo ship if it sailed 10 hours later?

Correct answer:

t =  12.5 h

Step-by-step explanation:

v1=10 1.852=18.52 km/h v2=18 1.852=33.336 km/h  s1=s2   v1 (t+10)=v2 t 18.52 (t+10)=33.336 t  14.816t=185.2  t=252=12.5=252 h=12.5 h
