a burned house, Yohann, fire chief, arrives at the wheel of the tanker truck which contains 3000 liters of water. The firefighters connect 2 water lances to the tank and open them at the same time: - the large lance has a flow rate of 2000 liters per minute. -the small lance has a flow rate of 500 liters per minute. How long will it take for this truck's tank to be empty? Justice in your response.

Volume total = 3000 litres grand débit de lance = 2000 litres par minute débit de la petite lance = 500 litres par minute Débit net = 2000+500=2500 litres par minute Temps total nécessaire pour vider le réservoir = \frac{total\,volume}{net\,flow\,rate}=\frac{3000}{2500}=1,2 Ainsi, le temps nécessaire pour vider le réservoir est de 1,2 secondes
