Test: Time - 1

In one hour = 60 minutes
∴ In 2 hours = 2 x 60 = 120

2 hours 30 minutes = 2 × 60 + 30 minutes
= 150 minutes

1 hour = 60 minutes

so 1 min = 1/60 hr

240 min = 240 x 1/60 = 4 hours

Correct Answer :- D

Explanation:- 12 hrs is the am pm clock that time corresponding to p.m. in the 24 hour clock.

7 hours 25 mins - 3 hours 45 mins = 3 hours 40 mins

Difference between 2019 & 1998 is 21

53 - 21 = 32

The correct option is Option C.

We know, 

One quarter minute = 15 seconds

Now, the time difference between 6:15 p.m. and 6:18 p.m. is = 3 minutes

So, One whole minute has 60 seconds, which means 

= 60 / 15 = 4 quarters 

So, 3 minutes will have = 4 × 3 = 12 quarter minutes.

1 hour = 4 quarter hours 

60 seconds = 1 minute 120 second = 120/60 = 2 minutes .
∴ The time 120 seconds after 16:30 hours = 16:32 hours

The time from 12 midnight to 12 noon is the forenoon or the 1st half of the day denoted as a.m.

No. of hours of work per day = 6 hours 30 minutes No. of hours of work for 5 days = 6 hours 30 minutes × 5 = 30 hours 150 minutes 60 minutes = 1 hour
∴ 150 minutes = 2 hours 30 minutes
∴ 30 hours 150 minutes = 30 hours + 2 hours 30 minutes = 32 hours 30 minutes
