Answer :
To find Ram's average speed, convert the travel time to hours (0.2583 hours) and the distance to kilometers (0.9 km), then divide the distance by the time, resulting in an average speed of approximately 3.49 km/h, correct to two decimal places.
To calculate Ram's average speed in kilometers per hour (km/h), we first need to convert the time he took to reach his friend's house into hours. 15 minutes 30 seconds is equivalent to 15.5 minutes. Since there are 60 minutes in one hour, this time is equal to 15.5 minutes / 60, which is 0.2583 hours.
Now, we know that Ram covered a distance of 900 meters, which we need to convert into kilometers to match the speed units. There are 1,000 meters in one kilometer, so the distance is 900 meters / 1,000, equaling 0.9 kilometers.
The formula for average speed is distance divided by time. Therefore, Ram's average speed is 0.9 kilometers / 0.2583 hours, which equals approximately 3.485 km/h. This is Ram's average speed in kilometers per hour, correct to two decimal places.
