Africa is a huge continent with hundreds of different cultures. It's impossible to lump all "traditional African marriages" together!
I think the problem was I hadn't converted my units. Does this make sense now?
for c.) d=v*t where v=19.98 and t=2/3, 19.98*(2/3)= 13.32 (which is actually one decimal off of my answer oops)
Which would give B. as being 6:10, or maybe about 6:09 since the velocity is riiiight under 20
so 19.98 miles per hour (converting the mi/min to mph) would be my actual average i suppose whoops
I did (0.5)(10)(0.283+0.333) + (0.5)(10)(0.333+0.367) + (0.5)(10)(0.367+0.350) + (0.5)(10)(0.350+0.283) = 13.33 miles Avg value: (13.33) / 40 = 0.333 mi/min
THANK YOU oh my goodness, that was so simple I can't believe I missed that. Thanks a bunch. That makes perfect sense.
Alright, so if the question is asking for a * then I multiply both functions together, but if its asking for a ◦ then I plug in one function the the other? ps, Thanks for your help!
