Question

If a phone takes 1 hour 30 min 50sec to charge, then how much will it take to charge 40 phones

Answer 1

Time Taken by one phone = 1 hour 30 min 50sec

• 1 hour = 60minutes = 60 × 60 = 3600Second.
• 30 minutes = 60 × 30 = 1800Second

Time Taken by one phone = 3600Second + 1800+ 50

Time Taken by one phone = 5450 Second

• Time Taken to charge 40 phones = 5450 × 40
• Time Taken to charge 40 phones = 218000.

Answer 2

Answer:

2,18,000 seconds

Step-by-step explanation:

Time Taken by one phone = 1 hour 30 min 50sec

1 hour = 60minutes = 60 × 60 = 3600 Second.

30 minutes = 60 × 30 = 1800 Second

Time Taken by one phone = 3600 Seconds + 1800+ 50

Time Taken by one phone = 5450 Seconds

• Time Taken to charge 40 phones = 5450 * 40

• Time Taken to charge 40 phones = 218000.
