Question

Trina's car uses 10 gallons of gas to travel 120 miles.If she has 5 gallons of gas in a tank, how much more gas will she need to drive 204 miles?

Answer 1

Answer:

12 gallons of gas

Step-by-step explanation:

for traveling 120 miles we need 10 gallons

with one gallons I can travel how miles?

10g--120miles

1g--120/10

1ga-12miles

so if I want to travel 204 miles then how many gallons I need now

204/12=17gallons of gas

but she has only 5 gallons

so she need extra how many

x+5=17

x=17-5

x=12
