Question

Find linear functions f and g (in miles) that model the distances traveled by Jade and Jari as functions of t (in minutes).

a) f(t) = 0.5t, g(t) = 0.8t
b) f(t) = 0.8t, g(t) = 0.5t
c) f(t) = 0.2t, g(t) = 0.3t
d) f(t) = 0.3t, g(t) = 0.2t

Answer 1

The linear functions that model the distances traveled by Jade and Jari as functions of time are f(t) = 0.5t and g(t) = 0.8t, respectively.

Step-by-step explanation:

From the given options, the linear functions f and g that model the distances traveled by Jade and Jari as functions of time t are:

a) f(t) = 0.5t, g(t) = 0.8t

Example: If t = 10 minutes, the distance traveled by Jade would be f(10) = 0.5 * 10 = 5 miles, and the distance traveled by Jari would be g(10) = 0.8 * 10 = 8 miles.

b) f(t) = 0.8t, g(t) = 0.5t

c) f(t) = 0.2t, g(t) = 0.3t

d) f(t) = 0.3t, g(t) = 0.2t

Based on the given options, the correct answer is option a) f(t) = 0.5t, g(t) = 0.8t.
