Starting at home, ishaan traveled uphill to the grocery store for 12 minutes at just 15 mph. he then traveled back home along the same path downhill at a speed of 30 mph

Question is Incomplete, Complete Question is given below.

Starting at home, Ishaan traveled uphill to the grocery store for 12 minutes at just 15 mph. He then traveled back home along the same path downhill at a speed of 30 mph. What is his average speed for the entire trip from home to the grocery store and back?

The average speed for the entire trip from home to the grocery store and back is 20 mph.

Step-by-step explanation:

Given:

Ishaan traveled uphill to the grocery store for 12 minutes at just 15 mph.

Time taken by him = 12 minutes

Speed = 15 mph

Since since speed is given in miles per hour and time is in minute, So we convert time in hour.

Time taken by him =

Now Distance can be calculate by Multiplying speed with time.

So, distance traveled = Speed × time

Substituting the values we get;

Distance traveled =

Now Again, he traveled back home along the same path downhill = 3 miles

Speed of covering downhill = 30 mph

We will find the time required with this speed to travel the distance.

Time Taken  =

Now We need to find the Average speed.

Average speed can be calculated by dividing Total Distance with Total Time.

Average Speed  =

Average Speed  =

Making denominators common by taking LCM we get;

Average Speed  =

Hence Average speed for the entire trip from home to the grocery store and back is 20 mph.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
