1)

Which of the following vehicles travelled at the same speed on both the days?


A) A

B) C

C) F

D) B

E) None of these

Answer:

Option D

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

Clearly, B travelled at the same speed on both days.
