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.

We have the relation between gallon and liter

     1 gallon = 3.78541 liter

So 30000 gallon means 113,562.3 liters

So there is water of 113,562.3 liters in 1 kilometer

Which means 56,781.15 liters of water in 0.5 kilometer

Accidents occur when the water reaches 30,000 liters per 0.5 kilometer

Here 56,781.15 > 30,000

So the cars are in danger.
