A boat goes upstream 30 miles and downstream 44 miles in 10 hours It also goes upstream 40 miles and downstream 55 miles in 13 hours Find the rates of the stream and of the boat?
The speed of the stream is 3mph and that of the boat is 8mph.If vs is the speed of the stream, in mph and vb is the speed of the boat in mph, then:upstream speed = vb - vs mphdownstream speed = vb + vs mphThus:30/(vb-vs) + 44/(vb+vs) = 1040/(vb-vs) + 55/(vb+vs) = 13Multiplying both equations by (vb2-vs2) gives:30(vb+vs) + 44(vb-vs) = 10(vb2-vs2)40(vb+vs) + 55(vb-vs) = 13(vb2-vs2)which rearrange to:vb2-vs2 = (74vb - 14vs) / 10vb2-vs2 = (95vb - 15vs) / 13so, using the equality:(74vb - 14vs) / 10 = (95vb - 15vs) / 1312vb = 32vsvb = 8/3 vsthus using the first equation and the equality just worked out:10((8/3 vs)2 - vs2) = 74(8/3 vs) - 14vsvs10(64 / 9 - 1) = 74 x 8 / 3 - 14vs10(55)/9 = (592 - 42)/3vs550/9 = 550/3vs = 3 mphvb = 8/3 x 3 mph = 8 mph
What angle or side is common to SUV and vts?
If VS and vs are the same then that is the common side.
