How do you estimate 175.32 ÷ 3 =
geniusboy [140]

Answer:

  ≈ 58

Step-by-step explanation:

Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.

Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.

You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.

_____

The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.

The distance between two cities is 145 miles. A truck can cover this distance in 2. 5 hours. A car is 1. 5 times as fast as the
Sophie [7]

The relative speed of the car to the truck while moving towards each other is the sum of the speed of both vehicles.

  • The time it takes them to meet is <u>1 hour</u>

Reasons:

The distance between the cities, d = 145 miles

The time it takes a truck to cover the distance = 2.5 hours

The speed of the car = 1.5 × Th speed of the truck

Required:

The time it takes them to meet if they are moving towards each other.

Solution:

  • \displaystyle Speed = \mathbf{ \frac{Distance}{Time}}

\displaystyle Speed \ of \ the \ truck, \ v_{truck} = \frac{145 \ miles}{2.5 \ hours} = \mathbf{58 \ mph}

Therefore;

The speed of the car, v_{car} = 1.5 × 58 mph = 87 mph

At the time<em>, t</em>, the truck and the car meet, we have;

\mathbf{v_{car} \times t + v_{truck} \times t = d}

Which gives;

87 × t + 58 × t = 145

\displaystyle t = \mathbf{\frac{145}{87 + 58}} = 1

  • The time it takes them to meet, <em>t</em> = <u>1 hour</u>
