Answer:
Option E
Explanation:
Speeds of vehicles on Day 1:
A → $\frac{832}{16}$ = 52 Km/hr
B → $\frac{516}{12}$ = 43 Km/hr
C → $\frac{693}{11}$ = 63 Km/hr
D → $\frac{552}{12}$ = 46 Km/hr
E → $\frac{935}{17}$ = 55 Km/hr
F → $\frac{703}{19}$ = 37 Km/hr
Speeds of vehicles on Day 2:
A → $\frac{864}{16}$ = 54 Km/hr
B → $\frac{774}{18}$ = 43 Km/hr
C → $\frac{810}{18}$ = 45 Km/hr
D → $\frac{765}{15}$ = 51 Km/hr
E → $\frac{546}{14}$ = 39 Km/hr
F → $\frac{636}{12}$ = 53 Km/hr
Speed of C on Day 2 = 45 km/hr
= $\left(45\times\frac{5}{18}\right)$ m/s = 12.5 m/s
