Jacob and issac decided to run to the basketball court after school the basketball court is 5 1/4 Miles from school the boys run
GenaCL600 [577]

Answer: 1\dfrac{5}{9}\text{ minutes}

Step-by-step explanation:

Complete question is provided in the attachment below.

Given: Jacob and Issac decided to run to the basketball court

Distance between basketball court and school = 5\dfrac{1}{4} miles

=\dfrac{21}{4} miles

Speed = 3\dfrac{3}{8} miles per hour

=\dfrac{27}{8} miles per hour

Since, time = (distance) ÷ ( speed)

Now, the time taken by boys to arrive at the basketball court = \dfrac{21}{4}\div\dfrac{27}{8} hours

=\dfrac{21}{4}\times\dfrac{8}{27}\\\\=\dfrac{7\times2}{9}=\dfrac{14}{9}\\\\=1\dfrac{5}{9}\text{ minutes}

Hence, the required length of time = 1\dfrac{5}{9}\text{ minutes}
