Ms jenkins has a grass lawn that is 24m wide and 30m long. mr jenkins cuts the grass at a reate of 9m per minute. how long will

Kisachek [45]

It will take Mr. Jenkins 1 hr and 20 minutes to cut all the grass.

To know how long it will take Mr. Jenkins to cut all the grass, get the total area of the lawn and divide it by the rate Mr. Jenkins cut the grass.

The area of the lawn can be calculated using the formula for the area of a rectangle given by:

A = l x w

where l is the length and w is the width.

Using this formula, the grass lawn that is 24 m wide and 30 m long has an area of:

A = l x w

where

l = 30 m

w = 24 m

A = 30 m x 24 m

A = 720 m^2

Meanwhile, the time it will take Mr. Jenkins to cut the grass lawn with an area of 720 m^2 can be computed using the rate.

amount = rate x time

720 m^2 = 9 m^2/minute x t

t = 720 / 9

t = 80 minutes = 1 hr 20 minutes

Walkway Over the Hudson, a bridge that crosses the Hudson River in Poughkeepsie, is 2.063 kilometers long. Anping Bridge, which

Pavlova-9 [17]

a. The total span of both bridges is 4.133 km.

When calculating the total of two different numbers, addition is the correct math operation to be used. We know that we need to add the length of the bridges together because the word <em>span</em> is the same as length. Also, the question asks about both bridges and uses the word <em>total. </em>2.063 + 2.07 = 4.133 km.

b. Leah and her dog will walk 4.126 km.

The question says that Leah walks across and back. This means she goes over the bridge two times. Times indicates that we should use multiplication for our math operation. Since she does the length two times, we need to multiply the length of the Walkway Over the Hudson bridge times 2. The math equation is 2.063 x 2 = 4.126 km.
