If she reads 50 pages of a book in 50 minutes, just divide 50 by 50.
50 / 50 = 1 She reads one page of a book a minute.
We know that
1 hour----------> 60 min
step 1
convert hours to minutes
<span>4:15---------> 4 hour +15 minutes------> 4*60+15-----> 255 minutes
step 2
</span><span>subtract 45 minutes
</span>255-45--------> 210 minutes
step 3
convert to hour
1 hour----------> 60 min
x-----------------> 210 min
X=210/60---------> X=3.5 hour
3.5 hour
that means
3 hour+0.5 hour
and 0.5 hour is-----------> 0.5*60----> 30 minutes
therefore
3.5 hour-------> 3 hour +30 minutes-------->3:30 pm
the answer is
3:30 pm
