Correct Answer: 32
Solution : Given: Total distance = 90 km Time = 1 hour Journey in first 25 minutes = 15.2 × 25 × 60 = 22800 m = 22.8 km Remaining distance = 90 – 22.8 = 67.2 km Remaining time = 60 – 25 = 35 minutes $\therefore$ Speed in m/s = $\frac{67.2}{35}×60×\frac{5}{18}$ = 32 m/s. Hence, the correct answer is 32.
