Answer 2

$\bf{\underline{Question\:1}}$

The distance between the school and a student's house is 1 km 875 m. Everyday she walks both ways. Find the total distance covered by her in six days.

$\bf{\underline{Solution:-}}$

Distance between home and school = 1875m

Total distance covered in one day = (1875m+1875m) = 3750m

Distance covered in six days = 3750 x 6 = 22500m

22 km 500 m distance covered in six

A vessel has 4 litres and 500 ml of curd. In how many glasses, each of 25 ml capacity,

can it be filled?

Capacity of curd in a vessel = 4 liters 500 ml = 4 × 1000 ml + 500 ml = 4500 ml

→ Capacity of one glass = 25ml

→ Number of glasses can be filled = 4500/25

$\bf{\underline{Therefore:-}}$

180 glasses can be filled by curd.
