You can put this solution on YOUR website! A boat travels 84 miles in 6 hours (with a constant speed). How much time will it traveling [sic] 378 kilometers?. [sic] A question mark is appropriate. The period is not needed.
----------------------
Either convert miles to kms, or kms to miles.
Then there are 2 ways you can do this one:
d = r*t
r = d/t
Find the rate, or speed.
Then,
d = r*t
t = d/r to find the time.
=============================
Or you can use a proportion.
84/6 = 378*k/t (k = converstion factor)
