car A covers X km per every litre of petrol car B covers (X + 5) km for every litre of petrol
1) write down the number of litres of petrol used by car A and car B in covering a distance of 400 km
2) if car A uses 4 litre of petrol more than car B in covering 400 km write down an equation in x and solve it to determine the number of litres of petrol used by car B for the journey

A uses 1 litre petrol for x km
B uesu 1 litre petrol for x+5 km
for A 1 litre = x km
(i) x=1
for B 1 litre = x+5
1 therefore A uses 5 litre of petrol more than B
if x=400 km
For A number of litre =
400
(ii) For B number of litre = x+5
400+5 =405
B uesu 1 litre petrol for x+5 km
for A 1 litre = x km
(i) x=1
for B 1 litre = x+5
1 therefore A uses 5 litre of petrol more than B
if x=400 km
For A number of litre =
400
(ii) For B number of litre = x+5
400+5 =405
