    Speed Time Distance Word Problem

    Hi, first time poster here! I really need some help with this word problem.

    A ferry goes between two ports that are 24 km apart. One day the ferry begins the trip 6 minutes late. In order to reach the other port at the correct time, it goes 8 km/h faster than usual. What is the ferry's normal speed?

    Thank you!!

    Solve simultaneously two equations: Vt=24 and (V+8)(t-0.1)=24. 0.1is 6min converted in hours.

    correction ...

    (v + 8)(t - 0.1) = 24

    faster speed ... less time
