Joseph is driving at a constant speed. after 1.5 hours he has driven a total distance of 75 miles.
rate = dist/time = 75/1.5 = 50 mph
-------------------------------
a) how far will Joseph drive in 4 hours at this rate?
distance = rate*time = 50*4 = 200 miles
------------------------
b) If D represents the distance Joseph has driven and t represents the time he has been driving write an equation for D in terms of t.
D = t*r
-----------------
c)Joseph needs to drive 175 miles to visit his grandma for Christmas. how many hours will it take him?
time = distance/rate = 175/50 = 7/2 = 3.5 hours
---------
