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.
