Answer 2

Calculating Time for Second Finger to Catch Up

To calculate the time it takes for the second finger to catch up with the first finger, we can use the formula:

Time = Distance / Relative Speed

Where: - Distance is the initial distance between the fingers - Relative Speed is the difference in speed between the two fingers

Given: - Speed of the first finger = 45 km/h - Speed of the second finger = 80 km/h

We need to find the time it takes for the second finger to catch up with the first finger.

Calculation

Using the formula, the time it takes for the second finger to catch up with the first finger is:

Time = 250 / (80 - 45) Time = 250 / 35 Time ≈ 7.14 hours

Therefore, the second finger will catch up with the first finger in approximately 7.14 hours.
