Question

Assertion(A): A car which takes 2hrs to travel 120km with a speed of 60km/her will take 3hrs to travel same distance with a speed of 40km/hr.
Reason(R): Speed and time are inversely proportional quantities.
a)Both A and R are true and R is the correct explanation for A.
b)Both A and R are true and R is not the correct explanation for A
c)A is true but R is false.
d)A is false but R is true​

Answer 1

Answer:

a. Both A and R are true and R is the correct explanation for A.

Step-by-step explanation:

time taken to travel 40 km/hr = distance traveled/ speed

= 120km/ 40 km/hr

= 3 hrs

As we decrease the speed of the car from 60 km/hr to 40 km/hr, the time taken to travel the distance increases from 2 hrs to 3 hrs, so speed and time are inversely proportional.

Answer 2

Answer:

Both A and R are TRUE.

Step-by-step explanation:

And R is the correct explanation for A
