Question

a car covers a certain distance in 2hr at 60km/h if it moves at 80km/h it will take ____ hour​

Answer 1

Answer:

speed = distance/ time

1.5 hour

Step-by-step explanation:

speed is inversely proportional to time

lets speed =s1 at time t1

speed=s2 at time t2

s1*t1= s2*t2

2*60=80*t2

t2= 2*60/80

t2=1.5 hour
