The Journey Begins
As the buses start moving from 
Hoshangabad, children sing at the top of 
their voices. Some look outside to enjoy 
the view of the green fields and the hills.
Indra — When will we reach Bhopal?
Ms. Asha — If we don't stop anywhere, we 
should reach there in 2 hours, that is 
around ______ o' clock.

Manjeet — Is it very far?
Mr. Bhimsen — It is about 70 km.
Ruby — Are we going to stop anywhere?
Mr. Rakesh — May be at Bhimbetka, about 50 km from here.
D If they go to Bhimbetka, they will reach there 
 — Before 10 o'clock
 — Between 10 o'clock and 11 o' clock
 — After 11 o' clock
As they are talking, Bahadur shouts — Hey! look at the Narmada. 
Everyone looks out of the windows.
Ruby — Wow! it is soooo long and so wide! 
  Let us guess how wide it is.

Gopi — Uhm---m, 100 metres? No, it is much more.
Can't say.
Victoria — It must be more than half a kilometre.
Ms. Asha — Look, it is written – 'This bridge is 756.82 metres
long'. So we can guess that the Narmada must be
about 500 metres wide at this place.
Sadaf — I just can't imagine 500 metres.
Ms. Asha — See, our bus is about 5 metres long. Imagine how
many buses can stand in a line on this bridge.
Everyone looks down at the river.
Mr. Rakesh — The water level now is quite low. It must be about
40 metres below the bridge.
Ms. Asha — But in the rainy season, the water had risen. Then
it was just about 15 metres below the bridge.
