In the roof spaces of two large barns that were 1,565 kilometres apart, there were two enormous pipistrelle bat roosts. In one barn, 1,346 bats were roosting, while in the other barn, 1,325 bats were roosting.

How many pipistrelle bats were roosting altogether in the two barns?

Did you know?

The place a bat lives and sleeps is called its roost. Hollow trees, caves and old buildings are common places for sleeping bats. Interestingly, these winged mammals hang upside-down because they cannot take to the air from the ground.
