Answer :
To calculate Ram's speed in km/h, time in minutes and seconds was converted to hours, and distance in meters to kilometers. The formula Speed = Distance / Time gave a result of approximately 3.48 km/h, which does not match the provided options. So the correct option is not listed here.
The student asked how to calculate Ram's average speed in kilometers per hour (km/h) when he took 15 minutes 30 seconds to reach his friend's house, which is 900 meters away.
To find the speed, we need to use the formula: Speed = Distance / Time.
Here, we first convert the time taken by Ram from minutes and seconds to hours to be consistent with the unit of speed (km/h).
So, 15 minutes 30 seconds is equivalent to 15.5 minutes, which is 15.5 / 60 hours or 0.2583 hours.
Then, we convert 900 meters to kilometers which is 0.9 km.
Now, applying the formula: Speed = Distance / Time = 0.9 km / 0.2583 hours.
After performing the calculation, we get the speed to be approximately 3.48 km/h.
Since none of the options given matches this value exactly, So the correct option is not listed here.
