During first 10s my velocity was #30" m/s"# Eastward.

(a) So my instantaneous speed at 6s will be #30" m/s"# Eastward.

During next 8s after first phase of 10s my velocity was #55" m/s"# Westward.

(b) So my instantaneous velocity at 14s will be #55" m/s"# Westward as this instant lies in the second interval of 8s.
