A car travels 357 miles in 5 hours and 15 minutes. How many miles does it travel per hour?
To find the miles traveled per hour, we need to divide the total distance traveled (357 miles) by the total time taken (5 hours and 15 minutes).
Since the time is given in hours and minutes, we need to convert the minutes to hours.
There are 60 minutes in one hour. So, 15 minutes is equal to 15/60 = 0.25 hours.
Thus, the total time taken is 5 hours + 0.25 hours = 5.25 hours.
Now, we can calculate the miles traveled per hour by dividing the total distance traveled by the total time taken:
Miles per hour = Distance / Time = 357 miles / 5.25 hours = 68 miles/hour.
Therefore, the car travels 68 miles per hour.
To find the number of miles the car travels per hour, we need to divide the total distance traveled by the total time taken.
First, we convert 5 hours and 15 minutes into hours. Since there are 60 minutes in an hour, 15 minutes can be expressed as 15/60 = 0.25 hours.
So, the total time taken is 5 + 0.25 = 5.25 hours.
Next, we divide the total distance traveled (357 miles) by the total time taken (5.25 hours).
357 miles / 5.25 hours = 68 miles per hour.
Therefore, the car travels at an average speed of 68 miles per hour.
To find how many miles the car travels per hour, we need to divide the total distance traveled by the total time taken.
First, let's convert the given time of 5 hours and 15 minutes into minutes. We can do this by multiplying 5 hours by 60 minutes (since there are 60 minutes in 1 hour) and then adding the extra 15 minutes.
5 hours × 60 minutes/hour = <<5*60=300>>300 minutes
So, the total time taken in minutes is 300 minutes + 15 minutes = 315 minutes.
Now, we can divide the total distance of 357 miles by the total time of 315 minutes to find the car's speed in miles per minute:
357 miles ÷ 315 minutes = 1.13 miles/minute
Finally, to find the car's speed in miles per hour, we need to convert miles per minute to miles per hour. Since there are 60 minutes in 1 hour, we can multiply the speed in miles per minute by 60:
1.13 miles/minute × 60 minutes/hour = 67.8 miles/hour
Therefore, the car travels at a speed of 67.8 miles per hour.
