Case Study 4: Work and Speed, Distance, Time (Variable Rates)
A community garden project received a contract to prepare **720 plant kits** for distribution to local schools. The project manager, Deepak, assigns three teams: **Team A**, **Team B** and **Team C**. From previous records, **Team A can prepare 40 kits per hour**, **Team B can prepare 30 kits per hour** and **Team C can prepare 20 kits per hour**.
They all start at 7:00 a.m. After some time Team B needs to leave for a delivery run, and the remaining teams continue. During the delivery, Deepak drives a small van to deliver a batch of prepared kits to a town **150 km** away. Due to roadworks, he covers the first **50 km at a reduced speed**, then returns to normal speed for the remaining distance. The case requires calculation of combined and partial work, time taken after one team leaves, adjustments when a team’s efficiency changes, and the split of travel time for two different speeds. Use the data strictly as given to answer the MCQs below.
