Correct question:
Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.
Answer:
Adrian should wake up by 6.14 am
Step-by-step explanation:
Given;
time to walk to school, = 15 mins
time to eat breakfast = 5/12 hour = 25 mins
time to get dressed = 0.7hour = 42 mins
time to shower = 0.15 hour = 9 mins
time Adrian needs to be in school = 7.45 am
Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;
7.45 am - 15 mins = 7.30 am
7.30 am - 25 mins = 7.05 am
7.05 am - 42 mins = 6.23 am
6.23 am - 9 mins = 6.14 am
Therefore, Adrian should wake up by 6.14 am
