Answer:
t + 3:45 = 11:20 am
Explanation:
A rocket is scheduled to launch from a command center in 3.75 hours.
The launch time is 11:20 am.
We need to know the time before 3.75 hours of 11:20 am.
3.75 hours = 3 hours (0.75 × 60) = 45 minutes
Let the current time be 't'
Now the equation will be
t + 3:45 = 11:20 am
t = 11:20 - 3:45
t = 7 : 35 am
Before 3.75 hours of 11:20 am it will be 7:35 am.
