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 = <<2000*12=24000>>24000
The new bridge has a capacity of 60/100*2000 = <<60/100*2000=1200>>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 = <<2000+1200=3200>>3200
There are 3200*12 = <<3200*12=38400>>38400 vehicles passing through the new bridge in a year.
Altogether, the two bridges have 38400+24000 = <<38400+24000=62400>>62400 vehicles passing through them in a year.
