A fire engine was rushing to a small fire, 15 miles away. The fire engine set out with 120 gallons of water, however, the water tank had a leak and the fire engine was losing water at the rate of 2 gallons per minute. The fire engine travelled at a constant 30 miles per hour. The fire required 50 gallons of water - did the fire engine have enough water when it arrived?

30 miles = one hour
15 miles = 1/2 hour or 30 minutes
2 gallons per minute x 30 minutes = 60 gallons.
60 gallons- 120 gallons = 60 gallons
They used 50 gallons which means they have 10 gallons left over. The answer is yes with 10 gallons to spare.
Actually they should replace the driver, because if they would have gone as fast as I normally do on the secondary roads, I do better then 30 miles an hour. How is it possible in the first sentence that he is rushing to the fire at 30 miles an hour? They must have put Grandma behind the wheel.

Start out with 120 gallons. Travel 15 miles at 30 miles per hour, that is 30 minutes. If you lose 2 gal per minute, that is 60 gallons lost on the way to the fire. 120 - 60 is 60 gallons left when arriving at the fire. If it only needed 50 gallons, then yes it had enough water when it arrived.

yes
it took the fire engine 30 minutes to get to the fire
they lost 60 gallons (what a waste of water!)
120-60=60

Yep. With 10 gallons to spare. Maybe they can spray down some little kids or something. You know, get the whole family involved.
Although, I think with the pressure in those fire hoses you might just kill a kid with a full on blast. Huh...
Sometimes you just got to live on the edge!
YEAH! WOOO!

If they hooked the hoses up quickly enough before too much water leaked out while getting hooked up. The leak didn't stop when the truck stopped, so maybe not enough water was left.
