The backgrounds on three computer screens are set to change after a specified amount of time, as
KengaRu [80]

Answer:

-6 7/hr= -6F per hour

Step-by-step explanation:

a rate of change can be defined as:

R=(total change in some quantity) (time in which the change happened)

In this case we know that the temperature dropped -30F in a given time, then we already know that:

Total change in some quanity =-30F now we know that this change took place between the 1:00pm and the 7:00 pm the total amount of ime between these two hours is:

T= (7.00 - 1.00 hr)= 6.00 hr

this means that the change happened =6 hours.

then we can replace these values in the above equation to get:

R=(-30F)/(6hr)=-6F/hr

this means that for each hours that passes the temperature decreases 6F

we also can write that this rate as:

R=-6F/HR =-6F per hour.

Step-by-step explanation:

Bike: 10 MPH

Time: 1/4 Hour

1/4 of 10 = 2.5

Distance travelled on bike: 2.5 miles

Train: 20 MPH

Time: 1/4 Hour

1/4 of 20 = 5

Distance travelled by train: 5 miles

Add the distances together.

5 + 2.5 = 7.5

7.5 miles
