Case Study 1: Time and Work; Speed, Distance, and Time
Rohan runs a small delivery service in his town. He has three delivery boys: **Amit**, **Bilal**, and **Charan**. Each of them works at a different efficiency level. Amit can complete a full packing and loading task in **12 hours**, Bilal in **8 hours**, and Charan in **6 hours**. Rohan usually assigns tasks depending on workload and deadlines. One day, he received a bulk order of **96 identical packages** that needed to be packed and dispatched before evening. To complete the task faster, he allowed all three workers to work together for some time. Later in the afternoon, Charan had to leave for another urgent assignment, and only Amit and Bilal continued working. After completing the packaging, Rohan himself drove the loaded vehicle to a nearby city located **180 km** away. The travel route had mixed traffic conditions. He drove the first **60 km** at a constant speed, then increased his speed for the remaining part of the journey to ensure that the delivery was made on time. The case requires students to understand concepts of work efficiency, combined work rate, time allocation, and speed-distance-time calculation in a real-life scenario.
