ivanzaharov [21]

Divide 15 by 3 then multiply that number by 5.
15/3=5
5 x 5 = 25 apple pies.

think of it like this:
How many small groups of [3 blueberry pies] was in the group of 15. the answer is 5. so if the baker makes 5 for every three, and there are 5 threes, then there will be 25 apple pies. because 5 times 5 is 25.

Shelly and her family are riding the Pikes Peak Cog Railway. The table shows the approximate distances the train has covered at

Radda [10]

Answer:

The equation that can be used to find the distance (d), the train will travel in any number of minutes (m) is d=0.12m

Step-by-step explanation:

we know that

distance = $\frac{speed}{time}$

From the table below

CASE 1:

When time is 5 minutes and distance is 0.6 miles

Speed = $\frac{Distance}{time}$

Speed = $\frac{0.6}{5}$

speed = 0.12

CASE 2:

When time is 8 minutes and distance is 0.96 miles

Speed = $\frac{Distance}{time}$

Speed = $\frac{0.96}{8}$

speed = 0.12

CASE 3:

When time is 11 minutes and distance is 1.32 miles

Speed = $\frac{Distance}{time}$

Speed = $\frac{1.32}{11}$

speed = 0.12

CASE 4:

When time is 14 minutes and distance is 1.68 miles

Speed = $\frac{Distance}{time}$

Speed = $\frac{1.68}{14}$

speed = 0.12

CASE 5:

When time is 17 minutes and distance is 2.04 miles

Speed = $\frac{Distance}{time}$

Speed = $\frac{2.04}{17}$

speed = 0.12

CASE 6:

When time is 20 minutes and distance is 2.4 miles

Speed = $\frac{Distance}{time}$

Speed = $\frac{2.4}{20}$

speed = 0.12

In all the cases we get the speed as 0.12

Hence the equation can be

d = 0.12 m

where d is the distance(in miles) and m is the time(in minutes)
