Problem Analysis

To solve this problem, we need to find the rate at which Dato and Nika work together and then use that information to determine how long it would take Dato to complete the entire job on his own.

Given Information

- Dato and Nika together complete the work in 4 hours. - If Dato works for 3 hours and Nika continues for 4 hours, 5/6 of the work will be done.

Solution

Let's first find the rate at which Dato and Nika work together. Then we can use this rate to calculate the time Dato would take to complete the entire job on his own.

Rate of Work

Let's assume the rate at which Dato works is D and the rate at which Nika works is N. According to the given information, we have: - Dato and Nika together complete the work in 4 hours, so their combined rate is 1/4 of the work per hour. - If Dato works for 3 hours and Nika continues for 4 hours, 5/6 of the work will be done. This gives us the equation: 3D + 4N = 5/6.

Calculating Dato's Rate

We can use the information above to calculate Dato's rate of work.

Calculating Dato's Time to Complete the Work

Once we have Dato's rate of work, we can use it to calculate how long it would take Dato to complete the entire job on his own.

Let's proceed with these calculations.
