for her book club, Sharon reads for 45 minutes each day. write an expression for the number of hours she reads in d days

Sagot :

n=(3/4)*h*d

--------------------

n=Number of hours she reads

h=Hour(s)

d=Days

--------------------

You see, with this formula - when d=2,

n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours

So, in the space of 2 days, she had spent 1.5 hours reading.

An expression for the number of hours she reads in d days is 0.75d hours

Further explanation

Some units that need to be recalled are as follows :

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

Speed is the rate of change of distance.

[tex]\large { \boxed {v = \frac{d}{t} } }[/tex]

v = speed ( m/s )

d = distance ( m )

t = time taken ( s )

Let's tackle the problem now!

Sharon reads for 45 minutes each day , it means that :

Time Interval → Duration of Reading

1 day → 45 minutes = 0.75 hours

2 days → 2 × 0.75 = 1.50 hours

3 days → 3 × 0.75 = 2.25 hours

.

.

.

d days → d × 0.75 = 0.75d hours

Conclusion :

The number of hours she reads in d days is 0.75d hours
