This is the answer to your question
Total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles
Answer:
8 and 2/3
Step-by-step explanation:
Divide 6.5 by 0.75 and you get
, or 8 and 2/3
Rewrite in standard form and use the form to find the vertex.
