SHTO8 km (2)30 km (3)72 km (4)96 km​

Answer 1

Answer:

2 hours 30 minute=(2×3600+30×60)sec

=(7200+1800)sec=9000sec

in 9000 sec she goes 9000×12 meter=108 km

Answer 2

Answer:

108 km

Step-by-step explanation:

1hr=60mins

2hr=60*2=120 mins

2hr 30 mins=120+30mins

2 hours 30 minutes=150 mins

1 min=60 sec

150 mins=150*60

150 mins=9000 secs  

1 second = 12 metres

9000 seconds = 12*9000

9000 sec=108000 m

1m=$\frac{1}{1000}$

108000 meters =  $\frac{108000}{1000}$

108 km in 2 hours 30 minutes
