Question

kellie walks 1/4 mile in 1/14 hour. at what rate does kellie walk

Answer 1

Do you know this relationship:
distance = rate x time ?
We know the distance traveled and the time of travel, so we just need to solve for rate.

Answer 2

It comes from the idea that, if you travel at a specific rate (say, miles per hour) for an amount of time (hours), the product is the distance traveled (miles/hour * hours = miles).
The question gives you a distance and a time:
Distance: \( 1/4 \) miles
Time: \( 1/14 \) hours
So that the relationship is:
\( \dfrac{1}{4} = \text{rate} \times \dfrac{1}{14} \)

Answer 3

From there, we only need to get rid of the 1/14 multiplied onto the rate to solve for rate. This can be done by dividing both sides by (1/14), or by multiplying both sides by 14.

Answer 4

mhm

Answer 5

In general, this relationship is good to know though:
\( \text{distance} = \text{rate} \times \text{time} \)
It is always true for average rate, so given any of two of the three variables, you can solve for the last.

Answer 6

i gott 3 1/2 as my answer

Answer 7

I think that looks good. :)
rate = 14/4 = 7/2 = 3.5 or 3 1/2

Answer 8

ok thnks
