Kwan hiked up a hill at 4 km/h and back down at 6 km/h. His total hiking time was 3 hours. How long did the trip up the hill tak
Leya [2.2K]

Let the time to hike up the hill  = t

As given that the total time time up and down is 3 hrs,  therefore

The time down the hill = 3-t

The distance up and down is the same.

Distance = speed * time

4t=6(3-t)

4t=18-6t

10t=18

t=1.8

Hence, time taken to uphill = 1.8 hours

Time taken to down hill = 3-18 = 1.2 hours

Suppose your new business made a profit during the first year of $3000. If the profit increased 12% per year, find the total of
mariarad [96]

Answer:

Therefore the total of all profit earned by the end of of the the first 5 years is $19,058.542.

Step-by-step explanation:

To find total profit earned per year, we need to use the compound growth formula.

The compound growth formula:

A= P(1+r)^t

A= Amount after t years

P= initial amount

r= rate of growth

t= time in year.

Given that,

New business made a profit during the first year of $3000.

If the profit increased 12% per year.

Here P= $3,000 and r =12%=0.12 , t=1 years

Plugging all value in the above  formula:

A=3000(1+0.12)^1

   =3000(1.12)

  =$3360

Profit after 2 year is $3,360.

Now, P= $3,000 and r =12%=0.12 , t=3 years

A=3000(1+0.12)^2

   =3000(1.12)²

   =$3763.2

Similar the profit at 4 year is

A=3000(1+0.12)^3

   =3000(1.12)³

   =$4214.784

The profit at 5th year is

A=3000(1+0.12)^4

   =3000(1.12)⁴

   =$4720.558

Therefore the total of all profit earned by the end of of the the first 5 years is=$(3,000+3360+3763.2+4214.784+4720.558)

          =$19,058.542
