Answer 1

Answer:

can you say how many minutes

Explanation:

but i know that the formula used will be s=ut+1/2at²

Answer 2

Speed of car in first 15 minutes = 40 km/h

Distance covered = speed × Time taken

60 minutes = 1 hour

15 minutes = 15/60 hour

Distance covered = 40×15/60=10km

Speed of car in next 15 minutes = 60 km/h

Distance covered = 60×15/60=15km

∴ Total distance covered = (10+15)km = 25 km

∴ 25 km is correct
