Question

1. A car covers a distance of 28.6 km in 2.2 litres of petrol. How much distance will it cover in one litre of petrol ?

with method

2. ∆ABC and ∆XYZ are congruent under the correspondence: ABC ↔ ZYX. Write the parts of

∆ABC that correspond to: (i)XY (ii) ∠Y (iii) ZX


​

Answer 1

1. To find the distance covered in litre petrol will be 28.6/2.2 = 13km covered in 1 litre petrol.
2. According to the figure attached ABC = ZYX

• XY = CB
• angle Y = angle B
• ZX = AC

Answer 2

Answer:

1. 13km

car uses 2.2 litres to cover 28.6 km

then by unitary method

car will use 1 litre of petrol to cover

(28.6÷2.2) km = 13km

$28.6 \div 2.2 = 13$

2. i) CB

ii) angle B

iii) AC
