Step-by-step explanation:

Here,

a). As the graph is given that in 10litre of petrol 10 km can be covered .

then, in 1 liter petrol 1 km is covered.

so,

i). ans is 30 km .

ii). ans is 42km.

b). rate of petrol (r)= RM. 2.30

travelled km= 36.

used petrol = 36 litres (as per the information in graph).

now, total cost (tc)= r×used petrol

or, tc= RM. 2.30 × 36

Therefore, the total amount is RM.82.2.

Hope it helps...
