Question

A driver is driving his car along a road as shown in Fig. 2.3. The driver makes sure that the speed-o-meter reads exactly 40 km/h. What happens to the speed of the car from P to Q?

• A. Speed remains constant
• B. Speed first increases then decreases
• C. Speed first decreases then increases
• D. Nothing can be decided

Answer 1

The correct option is A Speed remains constant

Since the speed-o-meter of the car reads exactly 40 km/h speed. This means that speed of the car remains constant always. So, speed of the car from P to Q remains constant.
