Question

The distance (d) in meters that an ant can travel varies directly with the amount of time (t) in hours it spends walking. Assume that an ant’s constant of proportionality is 18.

If an ant walks for 10 minutes, how far will it travel in meters?


If an ant traveled 22.5 meters, how long did it walk?


What does the constant of proportionality represent in this problem?

Answer 1

d = k t
d in meters
t in HOURS !
so d = 18 t
=================== now it gets tricky because we need t in hours
10 minutes = 10/60 = 1/6 hours
d = 18 (1/6) = 3 meters
========================
22.5 = 18 t
t = 1.25 hours
=======================
speed in meters per hour

Meters per minute would make more sense. I do not like your problems much.

Answer 2

they told you that d = 18t
now what?
