How do I calculate travel time from distance and speed?

Travel time = Distance ÷ Speed. For example, 300 miles at 60 mph takes 300 ÷ 60 = 5 hours. In metric: 480 km at 100 km/h takes 480 ÷ 100 = 4.8 hours (4 hours 48 minutes). Remember to use consistent units — miles with mph, or km with km/h.

How do I calculate arrival time?

Arrival time = Departure time + Travel time + Break time. For example, departing at 9:00 AM with a 3-hour journey and a 30-minute break: 9:00 AM + 3h + 0.5h = 12:30 PM arrival. This calculator does the time arithmetic automatically.

How long does it take to drive 100 miles?

At 60 mph: 100 ÷ 60 = 1 hour 40 minutes. At 70 mph: ≈ 1 hour 26 minutes. At 55 mph (with traffic): ≈ 1 hour 49 minutes. Always add 10–15% for real-world delays like traffic, stops, and construction.

What average speed should I use for driving calculations?

Use 55–65 mph (90–105 km/h) for interstate/highway travel. Use 20–35 mph (32–56 km/h) for city/urban driving. For mixed routes, 45–55 mph (72–88 km/h) is a reasonable average. For cycling, use 10–15 mph; for walking, 3–4 mph.

Travel Time Calculator

The Travel Time Calculator solves three travel problems in one tool. The Travel Time mode finds how long a journey will take given distance and speed — with optional departure time for a precise arrival time. The Distance mode works backwards: given a travel duration and speed, how far will you travel? The Speed mode tells you the average speed needed to cover a distance in a set time. All modes support miles and kilometers, and the travel time mode lets you add a break/stop duration to get an accurate real-world arrival time. Ideal for road trips, commute planning, flight estimates, or any journey.

lightbulb Planning Tips

•Use 50–55 mph avg for highway trips — real speed with traffic
•Add a 15–20 min break every 2 hours for long drives
•For flights, add 30–60 min for taxi + boarding to air time
•City commutes can be 30–50% slower than highway estimates

The Formula

The speed-distance-time relationship (d = v × t) is the foundation of all travel calculations. Rearranging: time = distance ÷ speed, and speed = distance ÷ time. To find arrival time, add the travel duration (and any planned breaks) to the departure time.

Time = Distance ÷ Speed | Distance = Speed × Time | Speed = Distance ÷ Time | Arrival = Departure + Travel Time + Break Time

tips_and_updates Pro Tips

Average highway speed with traffic delays is typically 50–55 mph (80–90 km/h), not the posted speed limit.

For long road trips, plan a 15–20 minute break every 2 hours — this improves safety and gives a more realistic arrival estimate.

Flight time calculators should use 500–600 mph (800–960 km/h) for commercial jets and add 30–60 min for taxiing and boarding.

Commute times in city traffic can be 30–50% longer than highway estimates — use a lower average speed (15–25 mph) for urban driving.

For cycling: flat terrain ≈ 12–15 mph (19–24 km/h); for walking: ≈ 3–4 mph (5–6 km/h).
