B Correct answer
Explanation

Speed increases every 3 hours. 0-3h: 56km/h (dist=168). 3-6h: 58km/h (dist=174). 6-9h: 60km/h (dist=180). 9-12h: 62km/h (dist=186). 12-15h: 64km/h (dist=192). 15-18h: 66km/h (dist=198). 18-21h: 68km/h (dist=204). 21-24h: 70km/h (dist=210). 24-27h: 72km/h (dist=216). 27-30h: 74km/h (dist=222). Sum = 168+174+180+186+192+198+204+210+216+222 = 1950.
