Answer 10

okay so, each of the points are marked for you
Kasai- (6 , 60,000) or 60,000/6
Zambezi- (6 , 42,000) or 42,000/6
Ubangi- (6 , 24,000) or 24,000/6
Aruwimi- (6 , 12,000) or 12,000/6

now what wee need to do is get it down into a single unit or in this case, a single seconds.
currently they are all marked at the 6 second line, so all we have to do is divide by 6 for each one. whichever ones are greater than 3000 are correct

I will show you how to do the first and then you can work out the rest and tell me what answer you got:::::

Kasai: 60,000 / 6 = 10,000/1 ..... this IS greater than 3000/1

now you do the rest and tell me which answers you get :)

Answer 14
