Ravi's Travel Statistics:
To solve this problem, we need to analyze Ravi's travel statistics when traveling to school at different speeds. Let's break it down step by step:

Given Information:
- Speed 1: 10 km/h (reaches school late by 8 minutes)
- Speed 2: 16 km/h (reaches school 10 minutes early)

Calculating Time Difference:
Let's calculate the time difference between Ravi's arrival time for both speeds:

- Speed 1:
- Time taken = Distance / Speed = x km / 10 km/h = x/10 hours
- Late by 8 minutes = 8/60 hours
- Total time taken = x/10 hours + 8/60 hours

- Speed 2:
- Time taken = Distance / Speed = x km / 16 km/h = x/16 hours
- Early by 10 minutes = -10/60 hours
- Total time taken = x/16 hours - 10/60 hours

Equating Time Differences:
Since the distance traveled is the same for both speeds, we can equate the time differences:

x/10 + 8/60 = x/16 - 10/60

Solving the Equation:
Let's solve the equation to find the value of x (distance):

Multiply the entire equation by 240 (LCD of 10 and 16) to eliminate the denominators:

24x + 32 = 15x - 40

Subtract 15x from both sides and add 40 to both sides:

24x - 15x = -40 - 32

9x = -72

Divide by 9:

x = -8

Interpreting the Result:
The negative value of x indicates that Ravi's school is located 8 km in the opposite direction of his travel. Therefore, the distance from Ravi's house to the school is 8 km.

Calculating School Start Time:
To calculate the school start time, we need to know the time Ravi started his journey. Let's assume he started at 8:20 am.

If he travels at a speed of 10 km/h, he reaches school late by 8 minutes, so the school start time would be 8:20 am + 8 minutes = 8:28 am.

If he travels at a speed of 16 km/h, he reaches school 10 minutes early, so the school start time would be 8:20 am - 10 minutes = 8:10 am.

Conclusion:
Based on the given information and calculations, Ravi's school starts at either 8:28 am (when traveling at 10 km/h) or 8:10 am (when traveling at 16 km/h).
