Question

in t minutes,the time would be 8am.if 40 minutes ago,the he time was 3t minutes past 2.00 am,then find the present time?

Answer 1

    3t + 120 + 40 + t = 480
=> 4t + 160 = 480
=> 4t = 480 - 160
=> 4t = 320
=> t = 320/4
=>t = 80

Answer 2

Time is a continuum of successive events that take place in order, from the past through the present to the future. The present time is 6:40 am.

Let's start by using the information given in the problem to set up two equations:

Equation 1: Current time + t minutes = 8:00 am

Equation 2: Current time - 40 minutes = 2:00 am + 3t minutes

We can simplify Equation 2 by converting both times to minutes since midnight:

Equation 2: Current time - 40 minutes = 120 minutes + 3t minutes

Current time = 160 minutes + 3t minutes

Now we can substitute this expression for Current time into Equation 1:

160 minutes + 3t minutes + t minutes = 480 minutes

4t + 160 = 480

4t = 320

t = 80

So the current time is:

Current time = 160 minutes + 3t minutes

Current time = 160 minutes + 3(80) minutes

Current time = 400 minutes

To convert this back to standard time format, we can divide by 60 to get the number of hours and minutes past midnight:

400 minutes ÷ 60 = 6 hours and 40 minutes

Therefore, the present time is 6:40 am.
