A student observes a speed-time graph for a car that moves at a constant speed for 10 seconds and then accelerates for 5 seconds. How can the student use the graph to calculate the total distance covered during these 15 seconds?
Subject: General Awareness | Topic: Science | Difficulty: MEDIUM
Options
- (A) By reading the final speed at 15 seconds and multiplying by 15
- (B) By calculating the area under the speed-time graph for each section and adding them
- (C) By multiplying the total time by the average speed shown on the graph
- (D) By using only the area under the acceleration section
Verified Answer
Option (B): By calculating the area under the speed-time graph for each section and adding them
