Question

If a day is 1½ hour longer than a night, what is length of each? Assume that 1 day and 1 night together =24 hour​

Answer 1

Answer:

Hence, day and night are 12.30 hr and 11.25 hr long respectively.

Given:

• A day is 1½ hour longer than a night.

To find:

• The length of day and night if they together=24 hrs

Solution:

Let night be x hr

>> Day=x+1½

According to the given condition

>> x+1½+x=24

>> 2x=24 - 3/2

>> x=(48-3)/4

>> x=45/4=11.25 hr

>> Night=11.25 hr

>> Day=11.25+ 3/2=11.25+1.5=12.30

>> Day=12.30 hr

Hence, day and night are 12.30 hr and 11.25 hr long respectively.
