According to the question, Michelle walks at a speed of 320 feet per minute her friend Diana Liz 400 yards from the shelves house approximately how many minutes will Michelle need to walk from her house to Diana's house and back

First of all we have to work out in only a unit(since there are 2 units involved;feet and yards)

So,let's change the feet to yards

1 foot = 3 yards

X = 400 yards

X = 400 × 3

X = 1200 feet

Speed = distance/time

320 = 1200/x

X = 1200/320

X = 3.75 mins or 3 mins 45 secs
