Answer 1

Answer:

Explanation:yo

Answer 2

Answer:

1. a) - 365 days = 9125 hours. b) -24 hours = 86400 second. c) - 3720 seconds = 62 minutes
2. 120km/hr or 33.3m/s
3. 15000m/s × 18/5 = 54000km/hr
4. Amit's school bus travels at 36km/hr = 36×5/18 =10m/s....whereas Sushma's bus travels at 11m/s... Therefore Sushma's school bus travels faster.
5. 1km/hr=1000m/3600s

(since 1km=1000m & 1hr=3600 seconds)

1km/hr=10/36 m/s

=5/18 m/s
