The distance between town X and town Y is 124 kilometres and a car uses 25 litres of petrol to make the journey. after the engine has been tuned, fuel consumption is reduced by 2%. how much petrol is required to travel from town X to town Y and back after tuning? answer ASP
ALSO, ADD STEP BY STEP EXPLANATION PLEASE

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!!

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
