A fire engine travels seven miles to a fire at a speed of 36mph.

Its tank holds 500 gallons of water but it’s been leaking throughout the journey at a rate of 22.5 gallons per hour.

If the fire engine needs 497 gallons of water to put out the fire, will it succeed?

No is the answer

Time to arrive- 7/36 hr
Leak amount while travel- 22.5*7/36=4.375 gallons > (500-497)=3 gallons so not enough water to put fire out
