Step-by-step explanation:

Given

Shopper pushes a cart 50 m south down then turns 90 ^{\circ} west and moves 23 m.

he then makes $90^{\circ}$ turn and moves 14 m

(a)Largest possible displacement is when he turns towards south

Net displacement $=\sqrt{64^2+23^2}=68.0 m$

(b)Smallest displacement when he turns towards north

$=\sqrt{36^2+23^2}$

$=\sqrt{1825}=42.72 m$

10 people who build at the same rate can frame a house in 6 days. What fractional part of a house can 4 people frame a house in

Alina [70]

10 people who build at the same rate can frame a house in 6 days. That means it will take one person $10\times6=60$ days to finish the house.

Which means that it will take 4 people $\frac{60}{4}=15$ days to finish the house.

So, the fractional part of the house 4 people can frame in 3 days will be $\frac{3}{15}=\frac{1}{5}$

Thus, Option D is the correct answer.
