The

car

passes

a

huge

boulder

on

the

side

of

the

road.

‘That’s

a

gigantic

rock!’

your

sister

remarks.

‘I

wonder

what

it

weighs.’

The

car

zooms

across

a

bridge.

‘How

fast

are

we

going?’

you

ask.

‘Guess!’

your

mother

says.

‘Ninety

kilometres

an

hour?’

‘Close,’

your

mother

replies,

as

she

looks

at

the

car’s

speedometer.

We’re

going

95

kilometres

an

hour.’

‘What

time

is

it?’

your

sister

asks.

‘Guess!’

your

father

replies.

Your

sister

looks

outside

at

the

shadows

of

trees.

‘I

think

it’s

four

o’clock,’

she

announces.

Your

father

looks

at

his

watch.

‘Not

bad.

It’s

half-past

four.

We’re

getting

close

to

the

national

park

now.’

‘What

direction

is

the

park

from

here?’

you

ask.

Your

father

studies

the

map.

‘We

go

north

a

few

kilometres,

and

then

turn

west

into

the

park.’
