You are attempting to water some flowers in a garden and only have a leaky watering can to do so. After consulting your l°Cal agronomist, you know that the flowers need 2.1 kg of water to flourish. The watering can holds, when filled, 5.0 liters of water. The water leaks from the can at a rate of 0.12 kg/s. It takes 30 seconds to walk from the spigot where you fill the watering can to the brim to the flowers. Consider any water that leaks from the can while you are watering the flowers falls onto the flowers. How many trips between the spigot and the flower bed will you need to make in order to give the flowers the proper amount of water?
