Answer:
53.5 km/h
Step-by-step explanation:
Average speed = distance /time
Total time in hours = 30/60 + 12/60 + 45/60 + 15/60
= 0.5 + 0.2 + 0.75 + 0.25
= 1.7 hours
Distance = Speed / time
Total distance covered = (0.5*80) + (0.2*105) + (0.75*40)
= 40 + 21 + 30
= 91 km
Average speed of the entire trip = 91/1.7
= 53.5 km/ h
45x/45= 1,072/45
x= 23 (rounded)
but, 45(23) is only 1035, which makes 7 pictures left over
to use those 7 you need 38 more picture to divide it evenly (because 45-7 = 38)
