Answer this question:The country of Belize had a 5 lane bridge that had 2000 vehicles passing through it every month. They decided to build a new bridge that had twice the capacity of the old one, and the number of vehicles passing through the new one increased by 60% more than the old bridge. If the bridges work concurrently for a year, calculate the total number of vehicles that pass through the two bridges.
In a year with 12 months, the total number of vehicles passing through the old bridge is 2000 * 12 = 24000. The new bridge has a capacity of 60 / 100 * 2000 = 1200 more vehicles passing through it in a month than the old one. The total number of vehicles passing through the new bridge in a month is 2000 + 1200 = 3200. There are 3200 * 12 = 38400 vehicles passing through the new bridge in a year. Altogether, the two bridges have 38400 + 24000 = 62400 vehicles passing through them in a year.
The answer is 62400.

Answer this question:Lucy is listening to her favorite album while jumping rope. She can jump the rope 1 time per second. If the album's songs are all 3.5 minutes long and there are 10 songs, how many times will she jump rope?
She can jump her rope 60 times a minute because 60 x 1 = 60. The album is 35 minutes long because 10 x 3.5 = 35. She will jump her rope 2100 times during the album because 35 x 60 = 2100.
The answer is 2100.
