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