250 m

Step-by-step explanation:

Let the total length be x m.

$\therefore \: \frac{3}{5} \times x = 210 \\ x = 210 \times \frac{5}{3} \\ x = 70 \times 5 \\ x = 350 \: m \\ \\ \frac{5}{7} \times x = \frac{5}{7} \times 350 = 5 \times 50 = 250 \: m$

Round both numbers! :)
498 would round to the nearest hundred, 500 and 12 would round to the nearest ten, 10
You can then divide 500 and 10 which gets you 50.
Hope this helped :)
