On Mother's day, traffic at the tappan zee bridge was backed up for 15 miles. assuming a 2 lane highway leading onto the bridge and an average car length of 30 ft, how many cars were involved in the backup?
-
15 miles = 79,200 feet.
79,200 / 30 = 2,640
2,640 * 2 = 5,280
Multiply by 2 because double lanee.
Answer: 5,280
79,200 / 30 = 2,640
2,640 * 2 = 5,280
Multiply by 2 because double lanee.
Answer: 5,280
-
15 miles = 5280(15) = 79,200 feet per lane
79,200 ft/lane * 1/30 cars /ft = 2640 cars/lane
Total number of cars involved in back up = 2640 cars/lane * 2 lanes = 5280 cars
79,200 ft/lane * 1/30 cars /ft = 2640 cars/lane
Total number of cars involved in back up = 2640 cars/lane * 2 lanes = 5280 cars
-
2 lanes = 30 miles
30 x 5280 / 30 = 5280
5280 cars were involved in the back up.
30 x 5280 / 30 = 5280
5280 cars were involved in the back up.
