Answer: D. 20/3
Step-by-step explanation:
20/3 = 6.6 (repeating)
There’s 9 marbles in total and 5 green 2 red and 2 blue so if the first marble is green it would be a 5/9 chance of getting the marble same with the red but the fraction is 2/9
(300 ft/2.92 sec)(1 mi/ 5280 ft)(3600 sec/1 hour) = {3001·3600 miles)/(2.92·5280·1 hour) = 91080000 miles/15417.6 hours = 70.05 mph
15 in 5 hours would mean you are making 3 an hour, or one every 20 minutes.
