Distance

How

far

away

is

that

mountain?

How

tall

is

that

tree?

These

are

questions

about

distance.

Distance

is

the

amount

of

space

between

one

place

and

another.

In

ancient

times

Long

ago,

people

used

their

own

bodies –

arms,

hands,

fingers

and

feet —

as

the

units

of

measure

for

distance.
