#1) You are transporting ice cream from a warehouse to a local shop in a refrigerated van. Before you get on the road, the cargo area of the van is cooled to 15 °F. After 30 minutes of driving, you stop for gas and check the cargo area again. Disaster! The door isn't closing properly, and the cargo area of the van has warmed to 24 °F. It's a cool morning, at a constant 50 °F outside. If the cargo area of the van warms to 32 °F, then the ice cream will start to melt. But your destination is 30 more minutes away. Can you deliver the ice cream to the shop before it starts to melt?
