ioda

Answer:

Step-by-step explanation:

rate = d / t

rate = 192 / 3

rate = 64 miles / hour

Now you want to know how long it can take to get 448 miles

d = r * t

t = d / r

t = 448/64

t = 7 hours.

You could actually do it using proportions.

192/3 = 448/x                   Cross multiply

192*x = 448*3

192*x = 1344                    Divide by 192

x = 1344/192

x = 7

Do this the way you feel is the best way.
