Question

Give the rate in miles per hour. Round to the nearest tenth. Dev jogs 8 1/2 miles in 1 1/2 hours

Answer 1

Answer:

$R=\dfrac{17}{3}\ \text{miles/hour}$

Step-by-step explanation:

It is given that,

Distance covered, $d=8\dfrac{1}{2}\ \text{miles}$

Time taken, $t=1\dfrac{1}{2}\ \text{hours}$

We need to find the rate in miles per hour. It can be calculated by dividing distance covered and time taken as follows :

$R=\dfrac{8\dfrac{1}{2}\ \text{miles}}{1\dfrac{1}{2}\ \text{hour}}\\\\R=\dfrac{\dfrac{17}{2}}{\dfrac{3}{2}}\\\\R=\dfrac{17}{3}\ \text{miles/hour}$

Hence, Dev jogs at the rate of $\dfrac{17}{3}\ \text{miles/hour}$.
