Question

If it takes 10 hours to travel from North Carolina to Florida driving an

average speed of 60 mph, how long will it take to travel from North
Carolina to Florida driving an average speed of 70 mph?

Is it direct variation or indirect variation?

Answer 1

8.5 hrs? direct variation

Explanation:

60 per hour is 600 for 10 hours so 70 per hour to go 600 miles is 8.57142857143 in the calculator

600/60 =10

600/70 = 8.5

and its direct variation because on a graph 8.5 8.5 squares up for ever 1 square going over every time and the graph does curve but I haven't learned this stuff in years so I'm not 100% sure
