You would spend <em>$71.32</em> per week on gas.
<em>Step 1</em>. Convert <em>weeks to days
</em>
Time = 1 wk × (7 days/1 wk) = 7 days
<em>Step 2</em>. Calculate the <em>distance</em> travelled
Distance = 7days × 125 km/day = 875 km
<em>Step 3</em>. Convert <em>kilometres to miles
</em>
Distance = 875 km × (1 mi/1.609 km) = 543.8 mi
<em>Step 4</em>. Calculate the <em>gallons of gas
</em>
<em>V</em> = 543.8 mi × (1 gal/40.0 mi) = 13.60 gal
<em>Step 5</em>. Convert <em>gallons to litres</em>
<em>V</em> = 13.60 US gal × (3.785 L/1 US gal) = 51.46 L
<em>Step 6</em>. Calculate the <em>cost of the gas</em>
Cost = 51.46 L × (€1.10/1 L) = €56.60
<em>Step 7</em>. Convert <em>euros to dollars</em>
Cost = €56.60 × ($1.26/€1) = <em>$71.32
</em>
