Question

jerry is a judge. He hears 5 cases every 2 3/8 hours. Jerry hears caese at a constant rat. How many cases does he hear per hour

Answer 1

Answer:

The number of cases heard by Jerry per hour is $2\frac{21}{500}$

Step-by-step explanation:

The rate of hearing the cases is 5 cases in 2 3/8 hours.

Now, $2\frac{3}{8} = 2+\frac{3}{8} = 2 + 0.375 = 2.375$

⇒The judge hears 5 cases in 2.375 hours.

So, the number of cases per hour = $= \frac{\textrm{Total Number of cases heard}}{\textrm{Number of Hours}} = \frac{5}{2.375}$

                                                           = 2.105

Also, $2.105 = 2 + 0.105 = 2 + \frac{105}{1000} = 2+\frac{21}{500} = 2\frac{21}{500}$

Hence, the number of cases heard by Jerry per hour is $2\frac{21}{500}$
