In a thundering voice vote Sunday night, about 1,000 migrants at the gymnasium in Cordoba voted to try to make it to Mexico City on Monday, which would be their longest single-day journey yet since the caravan began — 178 miles (286 kilometers) by the shortest route. -Associated Press
Thousands of bone-tired Central Americans set their sights on Mexico City on Sunday after making a grueling journey...
Monday minus Sunday is one day. One day is 24 hours. If they walked for 24 hours straight they would still need to walk almost 5 miles per hour which is just short of a jog for most people.
They are not walking the entire distance or even most of it. They are hitching rides.
Must be that new math that they teach journalists at University.
