Answer 3

Calculating the Time Taken for the Trip

To calculate the time taken for the trip, we can use the formula: time = distance / speed

For the first part of the trip: - Distance = 15 km - Speed = 5 km/h

Using the formula, we can calculate the time taken for the first part of the trip: 15 km / 5 km/h = 3 hours

For the second part of the trip: - Distance = 12 km - Speed = 4 km/h

Using the formula, we can calculate the time taken for the second part of the trip: 12 km / 4 km/h = 3 hours

Total Time Taken

To find the total time taken for the trip, we can add the time taken for the first part of the trip to the time taken for the second part of the trip: 3 hours + 3 hours = 6 hours

So, the children were in the trip for 6 hours.
