Adrian's car gets about 12.5 kilometers per liter. He is planning a 1,600 kilometer trip. a) About how many liters of gas should Adrian plan to buy? Round your answer to the nearest liter.

b) At an average price of $0.90 US per liter, how much should Adrian expect to spend for gas?​

try multiplying how much the kilometers are with how much you need to spend on gas

[1] 128 litres.

[2] $115.2.

Step-by-step explanation:

(1) In 12.5km, car takes 1 litre.

In 1km, car takes 1/12.5

For 1,600km, 1/12.5 × 1600

= 128 litre of gas.

(2) For 1 liter, he pays $0.90

So, for 128 litres of gas, he pays:

= 128 × 0.90

= 115.2$.
