Answer:

18

Step-by-step explanation:

4 miles in 20 mins = 1/5 mile in 1 min

1 1/2 hours = 90 mins

1/5*90=18

Answer:

18 miles

Step-by-step explanation:

if Samantha can ride her bicycle 4 miles in 20 minutes, that means every 5 minutes she rides for a mile.

20 / 4 = 5

Using that info, we can solve this.

1 hr & 30 min = 90 min

90 / 5 = 18 miles

Help please I have a test tomorrow!!!!
Taya2010 [7]
For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract  or add to find the rate.

To convert from square miles to square feet,what operation will you use
Serga [27]

The correct one is multiplication.

-- Take the number of square miles.

-- Multiply it by the fraction      (5,280 feet / 1 mile)² .

-- After canceling things where possible, simplifying, and
cleaning up the product, what you have is the same area
expressed in square feet.
