Student question: "A train travels at 60 km/h for 2 hours and then at 80 km/h for 3 hours. What is the average speed of the train?"
Step 1: Calculate total distance
The total distance covered is the sum of distances covered in each segment.
Step 2: Apply distance formula
Distance = Speed × Time.
Step 3: Substitute values
Distance 1 = 60 km/h × 2 h = 120 km
Distance 2 = 80 km/h × 3 h = 240 km
Total Distance = 120 km + 240 km = 360 km
Total Time = 2 h + 3 h = 5 h
Average Speed = Total Distance / Total Time = 360 km / 5 h = 72 km/h
Final Answer:
The average speed of the train is 72 km/h.

Why Do General Students Struggle With General?

Indian students face unique challenges when tackling General subjects. Often, large coaching classes leave little room for individual doubt clearing, meaning a single missed concept can snowball into major confusion. NCERT textbooks, while foundational, sometimes lack the detailed, step-by-step explanations needed for complex problems, leaving students feeling lost. The pressure of last-minute revision before exams is immense, and finding quick, accurate solutions to doubts can be nearly impossible without a personal tutor. This constant struggle to get clear, instant answers to their questions leads to frustration and can impact overall performance. A significant 65% of Indian students report feeling stressed about academics, with doubt resolution being a major contributing factor [National Council of Educational Research and Training (NCERT), 2022]. This is where a smart ai question solver can make all the difference.
