*** The school
authority planned to conduct a mini marathon race within the school campus.
They decided that the running distance to be 2 kilometres. Is it possible to
have a school campus with circumference of 2km? Discuss with your friends of
how big the campus should be?**

**Given:** school campus circumference = 2km

**• **Yes, it is possible to have a school
campus with circumference of 2km.

**• **Whatever may be shape of the school if
the perimeter of the school is more than or equal to 2km a mini marathon race within
the school campus is possible.

*** Give other
options if it is not a big campus.**

**• **If the perimeter of the school is not
more than or equal to 2km running more than one time (i.e., 2, 3 .... Rounds) and
make the distance equal to 2km a mini marathon race within the school campus is
possible.

*** Is the distance
in the sea also calculated in kilometres? How is it possible to calculate the
distance in sea water? Explore!**

**• **Yes, the distance in the sea is also
calculated in kilometers.

**• **It is possible to calculate the distance
in sea water by special methods like radar method, echo method.

*** We know that the
distance between celestial bodies is calculated in terms of light year. (Ah!
Unit of distance in terms of year???)
Yes, it’s the distance travelled by light in one year. Now without calculator
find how many kilometres light would have travelled in a year. (No Calculator).
Get the speed of light from your class teacher.**

**Answer: **

**• **Light travels 3 × 10^{8} m in
one second or 3 lakhs kilometer in one second. In one year we have 365 days. The
total number of seconds in one year is equal to 365 × 24 × 60 × 60 = 3.153 × 10^{7}
second.

**• **1 light year = (3.153 × 10^{7})
× (3 × 10^{8}) = 9.46 × l0^{15}m.

*** We see that the
distances between Chennai and Madurai is ‘462’ kms. But from which point to
which point is this distance calculated?. As we are science students we need to

two railway stations? Discuss and figure it out. Check your answers with your
class teacher.**

**Answer: **

**• **If we travelling through the road it
is the distance between two bus stand. If we travelling through the train it is
the distance between two railway stations.
