Drive Time1h 40m
Arrival Time (if leaving now)06:10 PM
Knowing how long a drive will take helps you plan departure times, fuel stops, and meeting arrivals. This calculator divides the trip distance by your average speed to estimate travel time, breaking the answer into whole hours and minutes and projecting an arrival clock time based on leaving right now. It assumes a steady average speed, so build in your own buffer for traffic, rest stops, and weather.
Formula
time = distance ÷ speed
- distance
- Total trip distance (e.g. miles or kilometres)
- speed
- Average travel speed in matching units per hour
- time
- Estimated travel duration, shown as hours and minutes
How it works
- Enter the trip distance and your expected average speed in matching units (miles with mph, or kilometres with km/h).
- The tool divides distance by speed to get the total time in hours, then splits it into whole hours plus the remaining minutes (rounded to the nearest minute).
- It also adds the total travel minutes to the current time to show an estimated arrival clock time, assuming you depart immediately.
Worked example
A 150-mile drive at an average speed of 60 mph.
- Total time = 150 ÷ 60 = 2.5 hours.
- Whole hours = 2; remaining 0.5 hour × 60 = 30 minutes.
- Total minutes = 150, which is also added to the current time to project arrival.
2 hours 30 minutes of driving (150 minutes total), plus an arrival time based on your current departure.
Frequently asked questions
- Does this account for traffic or rest stops?
- No. It assumes a constant average speed for the whole trip, so it does not add time for traffic jams, fuel stops, or breaks. Lower the average speed you enter, or add your own buffer, to reflect real-world conditions.
- How is the arrival time calculated?
- The calculator adds the estimated travel minutes to the current clock time on your device, assuming you leave immediately. If you plan to depart later, shift the result forward by that delay.
- Can I use kilometres instead of miles?
- Yes, as long as the units match. Enter distance in kilometres and speed in km/h, or distance in miles and speed in mph — the division gives the same time either way.
- What if my speed varies during the trip?
- Use your overall average speed, which already blends highway and slower segments. For a long trip with mixed roads, an average somewhat below the highway limit usually gives a more realistic estimate.
