Question

The following graphs show the relation between time taken and speed of two different cars.

Is the speed of Car 1 greater than the speed of Car 2 during the time interval t = 1 min to t = 2 min?

• A. Yes
• B. No
• C. Can't be determined
• D. None of the above

Answer 1

The correct option is A Yes

Looking at the graphs for time = 1 min to time = 2 min, we get:


Graph of Car 1 is increasing while that for Car 2 is constant.

So, the graph for Car 1 is steeper. Hence, its speed must be higher.

∴ Car 1 has a greater speed than Car 2.
