Answer :
Base fee to drive a truck = $18.95
Money payed by Saeed at the end of his drive = $130.49
Money he had to pay for the distance he drove :-
[tex] = 130.49 - 18.95[/tex]
[tex] = $111.54[/tex]
Money payed by Saeed for the distance he drove = $111.54
Money charged for an hour's drive = 78 cents
78 cents = $0.78
Distance Saeed drove :-
[tex] = \frac{111.54}{0.78} [/tex]
[tex] \color{orange}= 143 \: km[/tex]
Therefore , Saeed drove the truck for 143 km .
