A stork delivers babies to families living on Dorchester avenue. The bird carries one baby at a time from its nest to each home on the street.

The distance between the nest and the first house is ​x​ meters, and the distances between adjacent houses is ​20​ meters.


When delivering a baby to the ​7th​ house on the street, the stork flies a round trip distance of ​290​ meters.

  1. Determine the value of ​x.

    [3]
    Part (a):
    x=meters
  2. Find the total distance, in kilometers, that the stork must fly to deliver ​32​ babies.
