Yuto and Lian are at train stations 1,880 kilometers apart. Yuto boards a train heading east at an average speed of 220 kilomete
Artyom0805 [142]
To solve this problem you must apply the proccedure shown below:
 1. You have that the distance traveled by Lian is "x" and the distance traveled by Yuto is 1880-x.

 2. You have that the formula for calculate the speed is:
 V=d/t

 V1=d1/t1
 250=x/t1

 V2=d2/t2
 220=1880-x/t2
 
 Where d is the distance and t is the time.

 3. The problem says that Lian and Yuto board the trains a<span>t the same time, therefore:
</span> t1=t2
 x/250=1880-x/220
 x=1000 km

 Therefore, the answer is: 1000 km.

The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
ValentinkaMS [17]

Answer:

Future Value = $ 12528.15

Step-by-step explanation:

The depreciation is applied to the car annually. The value of the car after depreciation in "n" no. of years can be given by the following formula:

Future\ Value = (Present\ Value)(1-depreciation\ rate)^n\\

where,

Future Value = ?

Present Value = $ 24000

Depreciation Rate = 15% = 0.15

n = no. of years = 4

Therefore,

Future\ Value = (\$ 24000)(1-0.15)^4

<u>Future Value = $ 12528.15</u>
