Question

anonymous · Answer

D = RT

vortish · Answer

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

anonymous · Answer

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

vortish · Answer

k thanks jb that makes sense

vortish · Answer

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

vortish · Answer

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

anonymous · Answer

120/20= 6mph not 10

vortish · Answer

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

anonymous · Answer

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

vortish · Answer

no problem and right
