If a car goes 20 miles in 30 minutes, the average speed is miles per hour.
Question
If a car goes 20 miles in 30 minutes, the average speed is miles per hour.
Solution
To calculate the average speed, you need to know the total distance traveled and the total time it took to travel that distance.
In this case, the car traveled 20 miles in 30 minutes.
First, you need to convert the time from minutes to hours because the speed is required in miles per hour. There are 60 minutes in an hour, so 30 minutes is equal to 30/60 = 0.5 hours.
Then, you calculate the average speed by dividing the total distance by the total time. So, the average speed is 20 miles / 0.5 hours = 40 miles per hour.
So, if a car goes 20 miles in 30 minutes, the average speed is 40 miles per hour.
