Question

2. Patricia decided to lose some weight and train in a gym. On the first week, she trained for one hour and decided to increase her training every week by 30 minutes. What is her total number of training hours at the end of one month?

Answer 1

➭ Gíven :-

Training done in first week = 1 hour

Time increased to gym = 30 minutes

To fínd :-

Total working hours in a month.

Solutíon :-

In a month there are 4 weeks...

So,

$\longrightarrow \bf \:1 \: hour + 30 \: minutes \times 4$

$\longrightarrow \bf \:60 + 30 = 90 \: minutes$

$\longrightarrow \bf \:90 \times 4 = 360$

Therefore,she had trained for 360 minutes i.e 6 hours.

Answer 2

Answer:

6 hr

Step-by-step explanation:

In 1st week:   1 hr = 60 min

  2nd        : 60 + 30 min

  3rd         : 60 + 30 + 30 min

  4th         : 60 + 30 + 30 + 30 min

Total min:  60 + 60 + 30 + 60 + 30 + 30 + 60 + 30 + 30 + 30

   ⇒ 4 times 60 + 6 times 30

   ⇒ 4(60) + 6(30)

   ⇒ 240 + 180 = 360 min

360 min = (360/60) hr = 6 hr
