The distance between Ben's house and the school is 2.6 km. The distance between the school and the church is 550. What is the total distance between Ben's house and the church?

1km = 1000m
Multiply distance from Bens house to the school by 1000 to get total distance in meters:
2.6km x 1000m = 2,600m
Now add the 2 distances together:
2600 m + 550m = 3,150 total meters.
