Answer 1

1) 12+3=15 км/ч скорость 2-го велосипедиста 2) 60/12=5 чассов был в пути 1-ый велосипедист 3) 60/15=4 часа был в пути 2-ой велосипедист 4) (4+2)-5=1 час раньше приехал 1-ый велосипедист

Answer 2

Problem Analysis

To solve this problem, we need to determine which cyclist will arrive at village B first. The first cyclist starts at 10:00 am with a speed of 12 kilometers per hour, and the second cyclist starts at 12:00 pm with a speed 3 kilometers per hour faster than the first cyclist. The distance between the villages A and B is 60 kilometers.

Solution

Let's calculate the time it takes for each cyclist to reach village B.

Time Calculation

The time taken by each cyclist to reach village B can be calculated using the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

For the first cyclist: \[ \text{Time}_1 = \frac{60}{12} = 5 \text{ hours} \]

For the second cyclist: \[ \text{Time}_2 = \frac{60}{(12+3)} = \frac{60}{15} = 4 \text{ hours} \]

Conclusion

The second cyclist will arrive at village B first, as they will take 4 hours to cover the distance, while the first cyclist will take 5 hours.
