adrian began riding his scooter at 7:00am. He stopped riding it at 8:10am. How long did adrian ride his scooter for?​
Alenkinab [10]

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
