If you hike 1/2 mile every 1/5 hour how far do you hike in two hours?

5 miles

Step-by-step explanation:

0.5 x 10

= 5

5 Miles

Step-by-step explanation:

1/5 of an hour would be 12 minutes. If it is 1/2 mile every 1/5 our, you hike 1 mile for 2/5.

1/5 = 1/2

2/5 = 1

3/5 = 1 1/2

4/5 = 2

5/5 = 2 1/2

So if 1 hour is 2 1/2 miles, you multiply it by 2, or add it withh its same number, which is,

5 miles.

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
