Cayden Spencer · Answer 1

F (x) = (5/6) m

Distance equals rate (r) • time. You're solving for the rate of travel in respect to m minutes. 75 miles were traveled in 90 minutes.

75 = 90r

75/90 = r. This simplifies to 5/6

Create a function for distance where f (x) is defined by the rate 5/6 multiplied my minutes m.
