Dana has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she run at a speed of 8 mph and walks back at a speed of 2 mph, how long should she plan to spend walking back

2hrs 40 minutes

Step-by-step explanation:

The formula for distance is expressed as:

#The time taken to run:

#The time taken to walk:

#Since the distances are the same:

Hence, Dana spends 2hrs 40 minutes walking back

just needed some points but try socratic

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
