Question

Suppose a weather reporter has mistakenly reported the amount of water that flooded 1 kilometer of a roadway to be 30,000 gallons. If car accidents occur when the water reaches 30,000 liters per 0.5 kilometer, would the cars be in danger of an accident? Explain your answer. (Hint: 1 liter = 0.26 gallons.)

Answer 1

This is a maths problem. You just need to calculate it.

Answer 2

I know but the problem is I dont know how to do that, im a little confused.

Answer 3

The first step is to convert from gallons to litres. Then you just need to figure out how many litres you have in half a kilometre (instead of the 1 kilometre given) and you'll have your answer.

Answer 4

ok so I did the calculations and there are 0.26 litres in one gallon then i multiplied 0.26 by 30000, and that gave me 78000, so there are 78000 litres in one kilometer but since i needed half a kilometer i divided 78000 by two which gave me 3,900 so the answer would be 3,900 litres of water per half kilometer so therefore the cars are not in danger of a car accident. Is that correct or not.

Answer 5

I haven't done the calculation myself, but it sounds right to me.

Answer 6

oh o.k thank you so much.

Answer 7

wait would i divide 7800 by two or 0.5

Answer 8

0.5 = 1/2, so you can either divide by 2 or multiply by 0.5
