In "t" hours, where


    25*t + 30*t = 210.


Solve this equation


    55t = 210

    t   = 210%2F55 = 42%2F11 hours = 39%2F11 hours.

We get problems from around the world both the UK and the USA.
Traveling or travelling depends on your audience.
Traveling is the preferred spelling in the U.S.
Travelling is the preferred spelling in the UK or in the Commonwealth.
This American-British spelling difference carries for other forms: traveled or travelled and traveler or traveller.
