Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which
is the decay parameter.
One appearance per two minutes.
This means that 
Measured in minutes, the time T until the next encounter is Exponential with what rate parameter?

So
Rate parameter of
