A vehicle covers 2,160 miles in 5.5 hours. What is the average speed of the vehicle to the nearest tenth.
I got 55.5, but I don't think it is correct.
2160mi/5.5hr = 2160/5.5 mi/hr = 392.7 mi/hr
How did you wind up with 55.5? Just a simple sanity check shows that 50*5 = 250, which is way below 2150.
No, really, it might be useful if you show the calculation you used.
For stuff like this, it's always useful to include the units. You know that speed is mi/hr, so you know you need to divide miles by hours.
To find the average speed, you need to divide the total distance traveled by the total time taken. In this case, the vehicle covered 2,160 miles in 5.5 hours.
To find the average speed, use the formula:
Average speed = Total distance / Total time
Plugging in the values:
Average speed = 2,160 miles / 5.5 hours
Calculating this:
Average speed ≈ 392.7 miles per hour
Rounding this to the nearest tenth:
Average speed ≈ 392.7 mph
Therefore, the average speed of the vehicle is approximately 392.7 miles per hour.
To find the average speed of a vehicle, you need to divide the total distance traveled by the time it took to cover that distance.
In this case, the vehicle covered 2,160 miles in 5.5 hours. To find the average speed, you divide the total distance (2,160 miles) by the time taken (5.5 hours):
Average speed = Total distance / Time taken
Average speed = 2160 miles / 5.5 hours
Now let's do the math:
Average speed = 392.7272 miles per hour
To round to the nearest tenth, you round the average speed to:
Average speed ≈ 392.7 miles per hour
So, the correct answer is approximately 392.7 miles per hour, not 55.5.
