d = 18 t
d is in meters BUT t is in HOURS
ten minutes is 10/60 = 1/6 hour !
d = 18 * 1/6 = 3 meters !!!!
22.5 meters = 18 t
t = 22.5 / 18 HOURS
which is (22.5/18) 60 = 17 MINUTES
CAREFUL about UNITS !!!!
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.
Write an equation to represent the proportional relationship between d and t using the information given.
*My answer d=18t*
If an ant walks for 10 minutes, how far will it travel?
*My answer 180 meters*
If an ant traveled 22.5 meters, how long did it walk?
*My answer ??? hours
