Kaylee conducted a scientific experiment. For a certain time, the temperature of a compound rose 1 1/2​ degrees every 3/5 of an hour. What was the rate, in degrees per hour, that the temperature of the compound rose? Enter your answer as a whole number, proper fraction, or mixed number in simplest form.

Sometimes we aren't certain whether to multiply or divide.

Tip:  In math, "per" means "divided by" so

"degrees per hour" means divide the degrees by the hours

3 / 2  degrees

–––––––––––––

3 / 5  hour

To divide by a fraction,

invert the divisor and

multiply.

3         5

–––  *  –––   deg/hr

2         3

The 3's cancel, leaving

5

–––   deg/hr

2

Which probably the simplist form is  2-1/2 deg/hr  (two and a half degrees per hour)

Given that the temperature rose 1 1/2 degrees every 3/5 of an hour, we can convert the given information into a rate per hour.

Let's calculate the change in temperature per hour:

First, we'll find the change in temperature for 1 hour.

Since 3/5 of an hour is equal to 1, we can say that in 1 hour, the temperature will rise by 1 1/2 degrees.

Therefore, the rate at which the temperature rose is 1 1/2 degrees per hour, which can also be written as a mixed number: 1 1/2.

So, the temperature rose at a rate of 1 1/2 degrees per hour. My-Estub.com Login
