These are estimates from the Riegel formula, T2 = T1 × (D2 ÷ D1)^1.06. They assume you’ve trained for the other distance, so treat them as a guide, not a promise.
Over 30 minutes, run/walk is a real plan
Run/walk intervals work well at this pace. Decide them before the start and the last kilometre gets easier.
Regular short runs build the base. Add a few minutes each week.
Start further back so you don’t get pulled out too fast.
