1) Gathering the data
Varies directly
175 miles for 5 hours.
245 miles?
2) Since this is a direct variation
Then we can set a proportion. Presuming the driver will remain constantly at the same speed.
175 miles--------------5 hours.
245 miles------------- t
Cross multiply
175t = 245 x 5
175t =1225
t=7
It would take 7 hours to drive 245 miles.
