40% of an hour in minutes and secs
olga55 [171]

Answer:

<em>40% of an hour </em><em>equals: </em><em>24 minutes </em>

<em>40% of an hour also </em><em>equals: </em><em>1440 seconds</em>

<u>Skills needed: Time Units Conversion</u>

Step-by-step explanation:

1) First, we need to understand how to convert between hours, minutes, and seconds.

There are 60 minutes in 1 hour ==> 1 hour = 60 minutes

There are 60 seconds in 1 minute ==> 1 minute = 60 seconds

- This means that there are 3600 seconds in 1 hour (60*60=3600)

- This also means that there are 60 minutes in 1 hour

2) We are trying to find how many minutes (or seconds) 40% of an hour is.

---> When converted to decimal, 40\%=\frac{40}{100}=0.4

40% of an hour = 0.4 hours

Since there are 60 minutes in an hour, there are 60*0.4 minutes in 0.4 hours. 60*0.4=24 so, 24 minutes in 0.4 hours.

Since there are 3600 seconds in an hour, there are 3600*0.4 seconds in 0.4 hours. 3600*0.4=1440 so, 1440 seconds in 0.4 hours.

Mark ran a mile in 7 1/2 minutes. His brother ran a mile in 6 1/6 minutes. How much more time does Mark take to run the mile?
Bas_tet [7]

Answer:

1 1/3 more minutes

Step-by-step explanation:

Lets first convert both times to improper fractions

7 1/2 -> 15/2 (Mark's Time)

6 1/6 -> 37/6 (Mark's Brother's Time)

Now we need common denominators

15/2 = 45/6

Now times to subtract Mark's time - Mark's Brother's Time = More Time

45/6 - 37/6 = 8/6 or 1 2/6 = 1 1/3
