The minute hand is 12 feet long, but the clock face is 22 feet in diameter.

Question

If the minute hand were twice as long, how much farther would it travel every hour?

Answer 1

In one hour the minute hand makes one revolution or one circumference.
if the minute had is 12 ft long, then the circumference is 2π(12) or 24π feet

if the minute had were 24 feet long, it would travel
2π(24) or 48π ft
which would be 24π ft farther.

BTW, that is one huge clock!
and the end of the minute hand would stick out way beyond the clock face.
You sure you don't have a typo here ?

Answer 2

It does seem like a typo to me too but that's what the paper says.
Thanks for the help. I will try this out and see what the teachers think.
