Answer 2

Calculating the Time for Two Cars to Reach a Distance of 510 Kilometers

To calculate the time it takes for two cars to reach a distance of 510 kilometers when traveling in opposite directions, we can use the formula:

Time = Distance / (Speed1 + Speed2)

Where: - Distance = 510 kilometers - Speed1 = Speed of the first car = 45 kilometers per hour - Speed2 = Speed of the second car = (45 + 12) kilometers per hour

Calculation

Using the given formula, we can calculate the time it takes for the two cars to reach a distance of 510 kilometers.

Time = 510 / (45 + (45 + 12))

Time = 510 / (45 + 57)

Time = 510 / 102

Time = 5 hours

So, it will take the two cars 5 hours to reach a distance of 510 kilometers when traveling in opposite directions.
