Bill = 315 divide 7 = 45
Bill drives 45 miles per hour.
Joanne = 414 divide 9 = 46
Joanne drives 46 miles per hour

Alisha = 235 in hours

Rich also has £400 pounds invest 3% compound interest . How many years does he need to invest the money to get at least £475
zepelin [54]

Answer: 6 years

Step-by-step explanation:

Formula to calculate compound amount: A=P(1+r)^t, where P= Principal , r=rate of interest, t= time

Given: P = £400, r = 3% = 0.03 , A= 475

Required equation: 400(1+0.03)^t\geq475

400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875

Taking log on both sides , we get

t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6

Hence, he needs to invest the money for 6 years to get atleast £475.
