Step-by-step explanation:

Remember math is a language

f(x) : A function of x where x can be <em>any</em><em> </em>number including a number you choose

when you see f(-1), this tells you what the function is at <em>this</em> given x value. So you substitute - 1 wherever you see x

a biker travel 5ft in .05seconds. At that same rate of speed , how far will the biker travel in 1minute?
Solnce55 [7]

Biker's rate is:

v = 5/0.5

v = 10 ft per sec

t = 1 min = 60 sec

d = the distance the biker travels in 1 minute

v = d/t

d = v*t

d = 10*60

d = 600 ft

The biker travels 600 feet in 1 minute
