The Hohmann transfer is the fuel-cheapest way between two circular orbits: one burn to enter the transfer ellipse, one to circularize. See the two Δv costs.

Δv burn 11.64

Δv burn 21.34

Total Δv2.99

Transfer time61.3

Governing equation

Δ v = \frac{μ}{90} (\frac{2 \cdot 200}{90 + 200} - 1) + \frac{μ}{200} (1 - \frac{2 \cdot 90}{90 + 200}) = 2.99

Reading this result: A moderate transfer (90 → 200, ~2.2×): burn 1 (1.64) enters the ellipse, burn 2 (1.34) circularizes. Bigger ratios cost more total Δv (2.99) and coast longer (61.3).
