A car travels 50 miles in 1 hour and 15 minutes. What is the average speed
50/1.25 = x/1
Cross multiply and solve for x.
To find the average speed of the car, you need to divide the total distance traveled by the total time taken.
First, let's convert the time from hours and minutes to just minutes. We know that there are 60 minutes in an hour, so we can convert 1 hour to 60 minutes:
1 hour = 1 * 60 minutes = 60 minutes
Now, we add this to the 15 minutes that were initially given:
Total time = 60 minutes + 15 minutes = 75 minutes
Now that we have the total time in minutes, we can calculate the average speed. We divide the distance traveled by the time taken:
Average speed = Distance / Time
Average speed = 50 miles / 75 minutes
Simplifying, we can divide 50 by 75 as well:
Average speed = 0.6667 miles/minute
So, the average speed of the car is approximately 0.6667 miles per minute.
