The speed appears to be 400 miles an hour. If you meant 400 miles, the speed is 50 miles an hour.
That depends on the speed. Pick a speed, then divide the distance by the speed. If you divide a distance in miles, by a speed in miles/hour, the answer will be in hours.
The car's average speed is 86.67 miles per hour.
Six hours.
To find out how many miles you have driven, you can use the formula: Distance = Speed × Time Given that you're traveling between 35 to 50 miles per hour and you've driven for 68.1 hours, we'll calculate the distance for both the minimum and maximum speeds: For minimum speed (35 miles per hour): Distance = 35 miles/hour × 68.1 hours For maximum speed (50 miles per hour): Distance = 50 miles/hour × 68.1 hours Let's calculate: For minimum speed: Distance = 35 miles/hour × 68.1 hours = 2383.5 miles For maximum speed: Distance = 50 miles/hour × 68.1 hours = 3405 miles So, you have driven between 2383.5 miles and 3405 miles, depending on whether you were traveling at the minimum or maximum speed.
The time it takes to drive 20 miles depends on the speed at which you are driving. If you are driving at a constant speed of 40 miles per hour, it would take you 0.5 hours to drive 20 miles (20 miles / 40 miles per hour = 0.5 hours). If you are driving at a constant speed of 60 miles per hour, it would take you 0.33 hours to drive 20 miles (20 miles / 60 miles per hour = 0.33 hours).
The train's average speed was 34.5 miles per hour.
Speed = Distance / Time = 1500 miles / 3 hours = 500 miles per hour
The car's average speed is 10.64 miles per hour.
The average speed is 2050/5 = 410 miles per hour.
The average speed would be 280 miles divided by 6 hours, which equals 46.67 miles per hour.
