(a) Calculate the increase in the speed of the car in the terms of m/s.
(b) Mention a positive action performed by Priyanka here.

Answer 1

Answer:

the speed have increased from 36 to 54 is equal to 18

Explanation:

Answer 2

(a) Calculate the increase in the speed of the car in the terms of m/s.

Given:

Initial velocity of the car = 36 km/h = 10 m/s

Increased velocity of the car = 54 km/h = 15 m/s

Now the increase in the speed of car will be

Increased velocity - initial velocity = 15 - 10 = 5 m/s

Therefore the increase in the speed of car is 5 m/s

(b) Mention a positive action performed by Priyanka here.

Positive action performed by Priyanka here is that she was aware while driving and her focus was on the road. Although she increased the speed of her car but as soon as the rikshaw approached near her car she applied brakes and avoided an accident.
