Answer 3

Calculation of Time Taken by Misha and Petya

To determine who took more time to cover the given distance, we need to calculate the time taken by both Misha and Petya.

Misha covered a distance of 12 km with a speed of 4 km/h. To calculate the time taken by Misha, we can use the formula:

Time = Distance / Speed

Substituting the values, we get:

Time taken by Misha = 12 km / 4 km/h = 3 hours.

Petya covered the same distance of 12 km with a speed of 3 km/h. Using the same formula, we can calculate the time taken by Petya:

Time taken by Petya = 12 km / 3 km/h = 4 hours.

Comparison of Time Taken

From the calculations, we can see that Misha took 3 hours to cover the distance, while Petya took 4 hours. Therefore, Misha took less time than Petya to cover the given distance.

The difference in time taken can be calculated by subtracting the time taken by Misha from the time taken by Petya:

Difference in time = Time taken by Petya - Time taken by Misha = 4 hours - 3 hours = 1 hour.

Therefore, Petya took 1 hour more than Misha to cover the given distance.
