Give more information and I’ll help
You’re so smart, I love questions like this. Hopefully you can solve it so I can know too!
One hour = 60 minutes
60-15=45 so I would just add your 45 minutes to your 2:15
2:15+:45= 3:00
so your answer will be 3:00 :)
To determine how far away Oscars grandpa lives you would need to divide 50 by 6. 50/6= 8 and 1 third, or 8.33
