Question

1. Dean Morimoto spends 1 hour 20 minutes get-

ting ready for work each day. After leaving his
house he walks 10 minutes to a restaurant.
There he spends 30 minutes eating breakfast.
Then he walks 5 minutes to a bus stop where
he catches a bus for a 25-minute ride to work.
What time must he get up to reach his office
by 9 A.M.?

Answer 1

He needs to get up at 6:30 am.

Explanation:

1. convert all time to minutes (easier to add times and you can later convert back to hours)
2. add all the minutes up
3. divide by 60
4. subtract the quotient from 9 (since that is the time he needs to get there)
5. you should get 6.5 which is 6:30
