A man cycles a distance of 20km in 150minutes.What was her average speed in Km/hr
To find the average speed in km/hr, we need to convert the given distance and time into the same unit.
First, let's convert 150 minutes to hours. Since there are 60 minutes in an hour, we divide 150 minutes by 60:
150 minutes / 60 minutes/hour = 2.5 hours
Now we can calculate the average speed:
Average speed = Distance / Time
Average speed = 20 km / 2.5 hours = 8 km/hr
Therefore, the man's average speed was 8 km/hr.
To find the average speed, we can use the formula:
Average speed = Total distance / Total time
The distance is given as 20 km and the time is given as 150 minutes. We need to convert the time from minutes to hours.
There are 60 minutes in 1 hour, so we can divide the given time by 60 to convert it to hours.
Total time = 150 minutes / 60 = 2.5 hours
Now that we have the distance and the time in hours, we can substitute these values into the formula:
Average speed = 20 km / 2.5 hours = 8 km/hr
Therefore, the man's average speed was 8 km/hr.
To calculate the average speed in km/hr, you need to convert the time from minutes to hours.
Step 1: Convert minutes to hours
Since there are 60 minutes in an hour, divide the given time (150 minutes) by 60 to get the time in hours.
150 minutes ÷ 60 = 2.5 hours
Step 2: Calculate average speed
Average speed is determined by dividing the distance traveled by the time taken.
Average speed = Distance ÷ Time
Average speed = 20 km ÷ 2.5 hours
Step 3: Calculate the result
Divide 20 km by 2.5 hours to get the average speed in km/hr.
20 km ÷ 2.5 hours = 8 km/hr
So, the man's average speed was 8 km/hr.
