In an endurance race, Rachel ran

Reil [10]

Answer:

$31\frac{1}{5}\ miles$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

The distance is equal to multiply the speed by the time

we have

$speed=9\frac{3}{5}\ \frac{miles}{hour}$

$time=3\frac{1}{4}\ hours$

$distance=(9\frac{3}{5})(3\frac{1}{4})$

Convert mixed number to an improper fraction

$9\frac{3}{5}=9+\frac{3}{5}=\frac{9*5+3}{5}=\frac{48}{5}$

$3\frac{1}{4}=3+\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}$

substitute

$distance=(\frac{48}{5})(\frac{13}{4})=\frac{624}{20}=31,2\ miles$

Convert to mixed number

$31.2\ mi=31+0.2=31+\frac{1}{5}=31\frac{1}{5}\ miles$

Estimate the quotient. Explain how u got your answer 77.5÷10.2

bazaltina [42]

Divide 77.5 by 10 = 7.75
Since we divide by 10.2 (and not 10), we **subtract** 2% of 7.75, which is about 0.155 to give 7.595. (error=-0.04%)

You can also simplify a little by approximating 2% of 7.75 as 0.15 to give 7.6 as your estimate. (error=+0.026%)

exact value = 7.598...
