Only the Singapore→Mumbai route is practical by car (5,075 km by road). The other route requires flying.
Delhi (India) has a population of 16,787,941 and is located in the North India region of Asia. As a major metropolis, it offers extensive international connections and diverse attractions.
Mumbai (India) has a population of 12,442,373 and is situated in West India, Asia. This major global city has multiple airports and world-class infrastructure.
Choose this route if your priority is reaching Delhi (India) — a city of 16,787,941 in the North India region of Asia. Despite being the longer of the two at 4,157 km, it makes sense when Delhi itself is the destination, the schedule fits better, or ticket prices are noticeably lower. This is a fly-only route in practice — overland travel is not realistic at 4,157 km. The initial bearing is 319° (NW), so a great-circle flight leaves Singapore heading roughly NW.
This route is the right call if you are heading to Mumbai (India) — a city of 12,442,373 in the West India region of Asia. It is also the shorter of the two at 3,904 km, saving about 19 min of flying and around 64 kg of CO₂ per passenger. Driving is feasible — expect roughly 5,075 km of road and a fuel cost in the $508 USD range. Departing Singapore, the great-circle bearing toward Mumbai is 302° (WNW).

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
