The total distance of the sea route from Mumbai to Chennai is 2,700 km. A ship starting from Mumbai first reaches the Cochin port, travelling 1,083 km by sea. How much more distance does it have to travel to reach the Chennai port?

Correct Answer

Given: Total distance = 2,700 km Distance traveled = 1,083 km

Formula: Remaining distance = Total distance - Distance traveled

Substitution: Remaining distance = 2,700 - 1,083

Calculation: 2,700 - 1,083 = 1,617

Answer: The ship has to travel 1,617 km more to reach Chennai.

Explanation

The chapter demonstrates subtraction of large numbers using place value. 2,700 - 1,083: We need to borrow. Ones: 10-3=7, Tens: 9-8=1, Hundreds: 16-10=6 (after borrowing), Thousands: 1-0=1. Answer: 1,617 km.

Solution Steps

  1. Step 1: Set up subtraction: 2,700 - 1,083

  2. Step 2: Ones: 0 - 3 cannot be done, borrow from tens. But tens is 0, so borrow from hundreds. Hundreds becomes 6, tens become 10, then borrow from tens. Ones: 10 - 3 = 7

  3. Step 3: Tens: 9 - 8 = 1

  4. Step 4: Hundreds: 6 - 0 = 6

  5. Step 5: Thousands: 1 - 0 = 1

  6. Step 6: Answer: 1,617 km
