Question

Nate and Chris were walking along theriver, throwing stones into the watey, Everythree steps, they would each throw onestone. If they each walked ninety steps,how many stones would they throw intothe river altogether?

Answer 1

So, two boys walk together. Every three steps, each one throws one stone.

They walk 90 steps. At steps number 3, 6, 9, 12, 15, 18 and so on they throw stones. So they do it 90/3 times. 30 times.

30x2=60

60 stones altogether.
