Answer:
A= 1000(1+.06)^3 answer is A=1191.016
Step-by-step explanation:
first the formula is A=a(1 + or- R)^t
A=total
a=money or amount
R=rate it increase or decrease (percent) change to decimal
T=times,years,months ect..
Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
