what a stupid thing to say mjwman
they ask because -
maybe the dont drive,
maybe they are planning to see if something is affordable,
maybe they dont know what car they will drive,
maybe they have no idea what their petrol consumption is because they only do short journeys so not sure how to work it out
maybe they are hiring one,
maybe they have to start making this journey and want ot work out the best way before comitting
maybe they dont know how much petrol costs and what to decide whther itd be worth them buying a car than getting the train every day
maybe they are working out how much they will need to pay their friend in pretol costs because they are driving them,
maybe they are very young an dont know abiut this sort of thing
maybe they ask for all sorts of reasons
and most of all they ask necause this is answerbank and maybe someone here drives this route often an can answer in seconds rather than having to work it all out in miles, gallons, pence etc
and the reason they are not specific is maybe because they just want a genral figure, a guess, a ball park to give them an idea of what to expect, or because they dont have those details to give, because they dont know them or they dont have the car yet to find out
