.
Car A: (10km/L)(2.352)=23.52 mi/gal
Car B: (18km/L)(2.352)=42.34 mi/gal
Car C: (24km/L)(2.352)=56.45 mi/gal
.
From A to B:
(250 mi)/(23.52 mi/gal)=10.63 gal
From B to C:
(175 mi)/(42.34 mi/gal)=4.13 gal
From C to A:
(320 mi)/(56.45 mi/gal)=5.67 gal
Total:
Gallons: 10.63 gal+4.13 gal+5.67 gal=20.43 gal
Dollars: (20.43 gal)($4.25/gal)=$86.83
Euros: (0.85 euro/dollar)($86.83)=73.80 euros.
