15 minutes after 10:30 is 10:45. This is because you add 15 minutes to the original time of 10:30. To calculate this, you can add 10 minutes to get to 10:40, and then add another 5 minutes to reach 10:45.
At 15 km/hour you will have run 10km in 40 minutes.
6 hours 15 minutes = 375 minutes 2 hours 40 minutes = 160 minutes 375 minutes - 160 minutes = 215 minutes = 3 hours 35 minutes
To determine the time 40 minutes before a specific moment, you would subtract 40 minutes from that time. For example, if the current time is 3:00 PM, 40 minutes before would be 2:20 PM. If you provide a specific time, I can give you the exact answer.
40.25 hours or 40 hours 15 minutes.
Time = Distance/Speed = 10/40 = 0.25 hours = 15 minutes.

To determine when you will overtake your brother, we need to find the time it takes for the difference in your walking speeds to cover the distance between you. Since your brother leaves 5 minutes earlier and walks for 40 minutes, he will have covered 40/5 = 8 minutes of distance by the time you leave. You take 30 minutes to walk the same distance, so you gain 30-8 = 22 minutes on your brother every time you both leave. Therefore, you will overtake your brother 22 minutes after you leave, which would be at 7:22 AM.
It is 40 mph
3 hours 15 minutes minus 1 hour 35 minutes = 1 hour and 40 minutes
