1615/170 simplify show work
Sloan [31]
1615/170

We first need to convert this into a proper fraction. Which means that the denominator must be larger than the numerator for it to be proper. Also, since 1615 is BIGGER than 170, we will end up with a mixed fraction. A mixed fraction always has a whole number.

1615 can go into 170 how many times?

9 times

170*9 = 1530

Now subtract.

1615 - 1530 = 85

Now we have our mixed fraction:  9  85/170

Now we must simplify the fraction.

85/5 = 17
170/5 = 34

17/34 is the smallest possible fraction we can get. 

9 17/34

Final answer:  9  \frac{17}{34}

Answer:

a.) Time = 6 hours

b.) Average Speed = 410 miles per hours

c.) Distance = 196 miles

Step-by-step explanation:

<h3><u>a.</u>)</h3>

A coach drives 360 miles at a speed of 60 mph.

So,

Time = Distance ÷ Speed

Time = 360 ÷ 60

Time = 6 hours

<h3><u>b.</u>)</h3>

A plan flies 1640 miles in 4 hours.

So,

Average Speed = Distance ÷ Time

Average Speed = 1640 ÷ 4

Average Speed = 410 miles per hours

<h3><u>c.</u>)</h3>

A bus drives 3½ hour at an average Speed of 56 mph.

So,

3½ hour = 3.5 hour

Distance = Average Speed × Time

Distance = 56 × 3.5

Distance = 196 miles
