Sagot :
Answer:
49 litres of petrol are needed to travel from town X to town Y and back.
Step-by-step explanation:
Well, first off, the variable X and Y, as well as the distance given (124 km) aren't important pieces of information in this equation. They're only there to throw you off and confuse you.
25L of p (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less p than before it was tuned.
2%/100 = 0.02
0.02 * 25L = 0.5L
25L - 0.5L = 24.5L
Now, don't forget, at the end of the word problem we're asked how many litres of p would be required to travel from x to y AND BACK. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)
Good luck!!
