Answer:
The answer is C.
Step-by-step explanation:
First, you have to find the interest amount after 6 years. In order to do this, you have to subtract :
![3967.50 - 3450 = 517.50](https://tex.z-dn.net/?f=3967.50%20-%203450%20%3D%20517.50)
Next, you have to apply simple interest formula, I = (P×R×T)/100 where I repesents interest amount, P is priciple, R is interest rate and T is number of years :
![i = \frac{prt}{100}](https://tex.z-dn.net/?f=i%20%3D%20%20%5Cfrac%7Bprt%7D%7B100%7D%20)
![let \: i = 517.50,p = 3450,t = 6](https://tex.z-dn.net/?f=let%20%5C%3A%20i%20%3D%20517.50%2Cp%20%3D%203450%2Ct%20%3D%206)
![517.50 = \frac{3450 \times r \times 6}{100}](https://tex.z-dn.net/?f=517.50%20%3D%20%20%5Cfrac%7B3450%20%5Ctimes%20r%20%5Ctimes%206%7D%7B100%7D%20)
![517.50 = \frac{20700r}{100}](https://tex.z-dn.net/?f=517.50%20%3D%20%20%5Cfrac%7B20700r%7D%7B100%7D%20)
![51750 = 20700r](https://tex.z-dn.net/?f=51750%20%3D%2020700r)
![\frac{51750}{20700} = r](https://tex.z-dn.net/?f=%20%5Cfrac%7B51750%7D%7B20700%7D%20%20%3D%20r)
![r = 2.5\%](https://tex.z-dn.net/?f=r%20%3D%202.5%5C%25)
Answer:
C) 1/2
Step-by-step explanation:
there are two more choices and Blues Brothers is only one of those
The 4 is in the ten thousands place
Speed=distance / time ⇒ time=distance / speed.
Data:
distance=17.6 km
speed=11 km/h.
Therefore:
Time=17.6 Km / (11 Km/h)=1.6 hours
Answer: 1.6 hours.
