Answer:
100 minutes
Step-by-step explanation:
Given data
Total distaance= 400meters
Speed= 4m/s
We know that the expression for speed is
Speed= distance/time
substitute to find time
4= 400/time
time= 400/4
time= 100 minutes
slope=1.5
y=1.5x+4
x=#of miles
y=price
f(x) = x³ – 2x² – x + 2
0 = x3 – 2x2 – x + 2
(x-2)(x-1)(x+1)=0
x1=-1
x2=1
x3=2
