Question

The launch time is 11:20 and a rocket is scheduled to launch from a command center in 3.75 how what time is it now?

Answer 1

To solve this problem, let us first make sure that the values are in similar format. So to make the two values in same format, let us first convert the launch time which is in clock time format into decimal form.

The given launch time is 11:20 which reads as 11 hour 20 minutes. Since there are 60 minutes in an hour, therefore:

20 minutes (1 hour / 60 minutes) = 0.33 hour

Therefore the launch time in decimal form is 11.33

 

Now we can subtract the value of 3.75 to know the time now:

time now = 11.33 – 3.75

time now = 7.58

 

Rewriting this in terms of clock format:

0.58 hour (60 minutes / hour) = 35 minutes

 

Therefore the time now is:

7:35
