Answer 2

let restaurant , first petrol pump and second petrol pump be A,B and C respectively.

distance between the restaurant and first petrol pump = AB = 7km

distance between the 1st petrol pump and 2nd petrol pump = BC = 5km

to find : AC

ans :

AB = AC + BC

=> AC = AB-BC = 7-5 = 2km

therefore, distance between the restaurant and the second petrol pump is 2km
