Answer:

The actual building is 13.3 feet tall.

Step-by-step explanation:

Let the actual height be 'x'.

Given that on a scale drawing with a scale of 1/20, the height of the building is 8 inches, the expression becomes

(1/20) × x = 8

x = 20 × 8 = 160 inches

We know that

  • 1 foot = 12 inches

Thus,

160 inches = 160/12 ≈ 13.3 feet

Therefore, the actual building is 13.3 feet tall.

A plane travels 236 miles in 1. 4 hours against the wind. On the return trip, it travels the same 236 miles in 1 hour. Find the
KIM [24]
Speed is given by the distance traveled divided by the time spent.

The net speed with which the plane traveled against the wind is given by \frac{236}{1.4} =168.57\ mi/hr while the speed with which the plane travelled in the return trip is given by \frac{236}{1} =236\ mi/hr 

Let the speed of the plane be v and the speed of the wind be w, then when the plane was traveling against the sun, we have, v - w = 168.57 and when the plane is travelling in the direction of the wind, we have, v + w = 236.

 Subtracting the first equation from the second equation, we have: 2w = 236 - 168.57 = 67.43

Thus, w = 67.43 / 2 = 33.715

Therefore, the speed of the wind is approximately 33.7 mi/hr.
