Answer:
Q11) 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.
Distance between school and house = 1km 875m
=1\times1,000\ +\ 8751×1,000 + 875 = 1,875m (1km=1,000m)
Distance covered by her daily = 1,875\times21,875×2 = 3,750m
Distance travelled by her in 6 days = 3,750\times6\ =\ 22,5003,750×6 = 22,500 = 22,500m
Therefore,
Total distance travelled by her in six days is 22,500m i.e, 22km 500m.
Step-by-step explanation:
Q12) 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 glass = 25ml
Capacity of vessel = 4l 500ml
=4\times1,000\ +\ 500\ \ \ =\ 4500ml=4×1,000 + 500 = 4500ml (1l = 1,000ml)
No. of glass that can be filled = 4,500\div25\ =\ 1804,500÷25 = 180
Therefore,
180 glasses can be filled by the vessel of curd.
