Philip rode his bicycle 9 2/5 miles per hour. if he rode for 3/4 of and hour, how many miles did he cover
adelina 88 [10]

Answer:

Distance he covers in \frac{3}{4} of an hour = 7\frac{1}{20} miles.

Step-by-step explanation:

Phillip rode his bicycle at 9\frac{2}{5} miles per hour.

To find distance he covers in \frac{3}{4} of an hour.

Solution:

Speed at which Phillip rides = 9\frac{2}{5} miles per hour

Time for which he cycles = \frac{3}{4} of an hour

Distance covered in miles =Speed\times Time = 9\frac{2}{5} \times \frac{3}{4}

To multiply mixed numbers we need to convert them to fractions.

[A\frac{b}{c}=\frac{Ac+b}{c}]

9\frac{2}{5} \times \frac{3}{4}

⇒ \frac{(9\times 5)+2}{5} \times \frac{3}{4}

⇒ \frac{47}{5} \times \frac{3}{4}

Then we simply multiply the numerators and denominators.

⇒\frac{141}{20}

Then we convert back to mixed fraction by dividing numerator by denominator and writing the quotient as whole number with fraction (remainder as numerator and denominator being the divisor)

⇒ 7\frac{1}{20} miles.

∴ Distance he covers in \frac{3}{4} of an hour = 7\frac{1}{20} miles.
