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

<h3>Further explanation</h3>

Some units that need to be recalled are as follows :

<em>1 day = 24 hours</em>

<em>1 hour = 60 minutes</em>

<em>1 minute = 60 seconds</em>

Speed is the rate of change of distance.

\large { \boxed {v = \frac{d}{t} } }

<em>v = speed ( m/s )</em>

<em>d = distance ( m )</em>

<em>t = time taken ( s )</em>

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

<h2>Conclusion :</h2>

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

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.

Forty-two people charter a bus for $788. Estimate the amount each person pays.<br> Your answer
max2010maxim [7]

Answer:

$20

Step-by-step explanation:

If 42 people equally share the bus price off 788 dollars then ech person would be expected to pay 788/42 = $18.76 (2dp) though I suppose if you needed to estimate it, you would round 788 to 800 and 42 down to 40 which would give you 800/40 = 20 dollars per person which is a pretty close estimate.

Hope this helped!
