If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².
We have the ratio:
Area of the smaler triangle = x
Area of the larger triangle = 567 cm²

Answer:
Adrian rode his scooter for a total of 70 minutes, or an hour and ten minutes.
Step-by-step explanation:
There are 60 minutes in an hour, so if Adrian started riding his scooter at 7:00AM, to get to 8:10AM he needs to add 70. Again, since there are 60 minutes in an hour, 70 minutes converts to one hour and 10 minutes. Adrian rode his scooter for 70 minutes, or an hour and ten minutes.
7:00 + :70 = 8:10
