The car arrives from city A to city B in 3 hours. How many hours will it take to go the same way if you increase the speed by 20%?

Given :-

To find :-

Solution :-

Let us assume the distance between A and B be x and the initial speed by y . After 20% increase in the speed , new speed will be ,

Speed = 120y/100

Speed = 6/5y

• According to the Question ,

Distance = Speed * Time

x = y * 3 hrs

x = 3y

And ,

t = Distance/Speed

t = x ÷ (6y/5)

t = 5x/6y

t = 5 (3y)/6y

t = 5/2 hrs

t = 2.5 hrs

Hence now it will take 2.5 hrs to go from A to B .

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

y= -2x+4, have a great day
