Answer:
We know that:
" Elapsed time is the time or difference between a beginning time and an ending time ".
Now the two different methods to find the elapsed time is:
Method 1:
Subtract 2:30 directly from 2:58.
2:58 - 2:30 = 0:28
Hence, the elapsed time is 28 minutes.
Method 2:
Round 2:58 to 3:00, subtract 2:30 from 3:00, and at the end subtract 2 to get the desired time(2:58 + 2 = 3:00)
( Since it is easy to calculate the whole numbers).
2:58 is approximately 3:00
3:00 - 2:30 = 30 min
30 min - 2 min = 28 min.
Hence, elapsed times is 28 minutes.
The 60% of the number is 48.
A percentage is a quantity or ratio expressed as a fraction of one hundred. It's sign is % .
It is given in the question that
if 25% of a number is 20, what is 60% of the number
Let the number be x
Making the expression from the given quation
(25/100) *x = 20
x = 20 * 100 / 25
x = 80
Therefore the number is 80
Then 60% of the number is
(60/100)*80
48
Therefore the 60% of the number is 48.

Set up a proportion, 20 over 25% and x over 60% and the answer is 48

Answer:
Martin spends 35 minutes exercising daily. Two equivalent expressions to find his exercise time in 7 days are '7 * 35' and '(7 * 10) + (7 * 25)'. Thus, Martin exercises for a total of 245 minutes in 7 days.
First, let's determine the total amount of time Martin exercises daily. He lifts weights for 10 minutes and runs on the treadmill for 25 minutes. Thus, the total time he spends exercising each day is 10 minutes (weightlifting) + 25 minutes (treadmill) = 35 minutes.
Two equivalent expressions for Martin's total exercise time in 7 days can be represented as:
In both cases, they lead to the same conclusion. Hence, the total time Martin spends exercising in 7 days is 7*35 =245 minutes.
