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 (◠‿◕)
