a boat traveled 210 miles downstream and back.the trip downstream took 10 hous.the trip back took 70hours.what is the speed of t
he boat in still water.what is the speed of the current
1 answer:
The boat rates are 21 mph and 3 mph.
to find the speed you rate times time equals the distance.
so you do,
10 × r = 210
the speed equals 21mph
70 × r = 210
the speed equals 3mph
my guess is the boat is going 21 mph and the current is 3 mph
Hope this helps
