Answer 1

The distance between Toronto and Helsinki is 4110 miles, and the distance between Helsinki and Moscow is 558 miles.

Explanation:

Let's assign variables to the unknown distances:

Distance from Toronto to Helsinki = x

Distance from Helsinki to Moscow = x - 3552

According to the given information, the total distance flown from NY to Moscow is 5015 miles, and the distance from NY to Toronto is 347 miles. Using these values, we can set up the equation:

347 + x + (x + x - 3552) = 5015

Simplifying the equation:

347 + 2x - 3552 = 5015

Combining like terms:

2x - 3205 = 5015

Adding 3205 to both sides:

2x = 8220

Dividing both sides by 2:

x = 4110

Therefore, the distance between Toronto and Helsinki is 4110 miles, and the distance between Helsinki and Moscow is 4110 - 3552 = 558 miles.
