The driving distance between Oban and Stranraer is 180 miles.
Dividing this distance by the fuel consumption, we get the total fuel used:
180 ÷ 8 = 22.5 gallons of fuel.
The total cost will be:
22.5 × 0.83 = 18.68 £
The journey will cost 18.68£ for fuel.
Simply find the area under the velocity curve. Over the first 3 second interval, the area is that of a trapezoid with bases 2 and 5, so that area/distance traveled is
. For the last 4 seconds, the area/distance is
.
Then the total distance traveled is
