Answer:

1) 57.5 km

2) 1 hour

3) 57.5 km/hr

Explanation:

1) Distance covered in first 30 minutes :

= speed×time

= 45×(30÷60)

= 22.5km

Distance covered in next 30 minutes :

= 70×(30÷60)

= 35km

Total distance travelled : (22.5+35)km = 57.5km

2) Total time taken : 30mins + 30mins = 1 hour

3) Average speed : total distance travelled ÷ total time taken

= (57.5 ÷ 1)

= 57.5 km/hr

Hope this helps (◠‿◕)
