Sasha lives 1,493 miles from her grandmother. One year, Sasha's family made 4 round trips to visit her grandmother. How many miles did they travel in all?
One round trip means that Sasha had to travel to her grandmother (1493 miles) and then back to her home (another 1493 miles). That means one round trip would be 2986 miles.
Four round trips would be four multiplied by 2986 miles (1 round trip's distance) to get a total of 11944 miles.
