Question

a tug boat goes 120 miles up stream in 20 hrs and the return trip takes 5 hrs find the speed of the tugboat with out a current

Answer 1

D = RT

Answer 2

so if d=rt is that the same as 120=20x

Answer 3

yup u just solve for rate in both equations. 120=5R and 120=20R then compare the answers and find rate without current

Answer 4

k thanks jb that makes sense

Answer 5

so you divide both equations by the so it would look like 120/5 and 120/20 to come up with R correct

Answer 6

so the first equation would have 24 and the second would be ten

Answer 7

120/20= 6mph not 10

Answer 8

that would be 15 so the answer would be 120 miles at 15 mph

Answer 9

actually because 120/5= speed without current (downstream) your answer would just be 24mph. Sorry

Answer 10

no problem and right

Answer 11

medal? ;) @vortish
