1)

What was the speed of vehicle C on Day 2 in terms of metres per second?


A) 15.3

B) 12.8

C) 11.5

D) 13.8

E) None of these

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
