That depends on your average speed. If your average speed is 60mph, then a little over 2 hours. If your average speed is 30mph, then it's going to be a little over 4 hours.
Avg speed is total distance over total time so it would 609 miles/ 2 hours whis is 304.5 mph
Your average speed over the 418 miles would be 62.23 miles per hour.
To find the average speed, we divide the total distance by the time taken. In this case, the man circumnavigated the Earth in 80 days, which is 24 hours/day * 80 days = 1920 hours. The total distance traveled is 6200 miles. Therefore, the average speed is 6200 miles / 1920 hours ≈ 3.23 miles per hour.
10.85 hours (approx). That assumes you can maintain an average speed of 65 mph over that length of time.
Time = Distance/Speed = 661/65 = 10.2 hours, approx. This assumes that you can maintain an average speed of 65 mph for over 10 hours even after allowing for fuelling and comfort stops.
Time = Distance/Speed = 6.15 hours approx. This assumes that you can maintain an average speed of 65 mph for over 6 hours - quite an unlikely event.
It will take 2 hours 42 minutes if you maintain an average speed of 87 mph over the whole 233-mile distance.
The average speed over the first 30 miles is equal to the average speed over the next 15 miles. You cannot guarantee that the speed was constant inbetween, though. The average speeds are 45 MPH for each leg.
The road distance is 261 miles, just over 6 hours at an average speed of 40 mph or 4.5 hours at 55 mph
Depends on (average) speed; at 50 mph then just over 14 hours at 60 mph then just under 12 hours and so on ...
That depends on your average speed. At 60 mph, it will take 84.92 hours. At 50 mph, it will take 101.9 hours. At 500 miles a day, it will take a little over ten days.
