Answer 1

The scale of map is 1 : 1,00,000.

Map distance from house to school = 2.5cm.

Original distance = 2.5*1,00,000 cm = 2,50,000cm .

We know that ,100 cm = 1m.

2,50,000 cm = 2,500m

We know that 1km = 1000m.

2500m = 2.5km.

$\therefore$ The House of Jatinder is 2.5 km far away from the school.

Answer 2

as the scale is 1:100000
so for 2.5 it will be 250000cm
100cm =1 m
1000 m =1km
1km = 1000*100=100000cm
so 250000 = 2.5 km
