the time it takes you to get to campus varies inveresly as your driving rate. Driving at a rate of 40 miles per hour, it takes 1.5 hours. How ong would the trip take you driving at a rate of 60 miles per hour?

• algebra -

40*1.5 = 60

60t = 60, so the time would be 1 hour

or, since time*speed = a constant

(3/2 speed)(2/3 time) = the same constant
2/3 of 1.5 hours is 1 hour.
