Answer 2

Problem Analysis

We have two ports that are 567 km apart. Captain Vrungel's yacht and Solnyshkin's ship set off towards each other simultaneously. Captain Vrungel's yacht covers 42 miles in a day, which is 7/9 of what Solnyshkin's ship covers in a day. We need to determine how many days it will take for the two seafarers to meet.

Solution

Let's assume that Solnyshkin's ship covers x miles in a day. According to the problem, Captain Vrungel's yacht covers 7/9 of what Solnyshkin's ship covers in a day. Therefore, Captain Vrungel's yacht covers (7/9)x miles in a day.

To find the number of days it takes for the two seafarers to meet, we can set up the following equation:

567 km = 42 miles/day * (7/9)x miles/day

Now, let's solve for x:

567 km = 42 * (7/9)x 567 km = (294/9)x x = (567 km * 9) / 294 x ≈ 17.2857 km/day

So, Solnyshkin's ship covers approximately 17.2857 km in a day.

Now, let's find the number of days it takes for the two seafarers to meet:

Number of days = Distance / Speed Number of days = 567 km / (42 miles/day + 17.2857 km/day)

Let's calculate the number of days:

Number of days ≈ 567 km / (42 miles/day + 17.2857 km/day) Number of days ≈ 567 km / (42 * 1.60934 km/day + 17.2857 km/day) Number of days ≈ 567 km / (67.119 km/day + 17.2857 km/day) Number of days ≈ 567 km / 84.4047 km/day Number of days ≈ 6.72 days

Therefore, it will take approximately 6.72 days for Captain Vrungel's yacht and Solnyshkin's ship to meet.
