Question
Steve is 3 years older than Tim and twice as old as Hannah. Tim is 2 years older than Hannah. How old are Steve,Tim and Hannah?
Answers
Steve
s = t+3
s = 2h
t = h+2
so, let's solve for Hannah.
t = h+2
t+3 = 2h, so t = 2h-3
That gives us
h+2 = 2h-3
h = 5
So, Hannah is 5, Tim is 7, Steve is 10 (which is twice as old as Hannah)
s = 2h
t = h+2
so, let's solve for Hannah.
t = h+2
t+3 = 2h, so t = 2h-3
That gives us
h+2 = 2h-3
h = 5
So, Hannah is 5, Tim is 7, Steve is 10 (which is twice as old as Hannah)
