Marvin solved the same problem using a number line. marvin jumped 100 to get to 487. next marvin jumped 3 to get 490. next marvin jumped 53 to get to 543. draw a number line. show marvin's jumps on top and show how far he jumped on the bottom of the number line as he is getting closer to 543.

Marvin jumped 156 to getting closer to 543.

Explanation:

It is given that Marvin jumped 100 to get to 487. It means the Marvin starting point was,

The Marvin jump shown on the above of the number line and how far he jumped is shown in below the number line.

The initial point is 387. Then he jump 100 to reach 487. Next Marvin jumped 3 to reach 490. Next Marvin jumped 53 to reach 543.

The total distance covered by him is,

It the sum of his jumps,
