Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required = 
time required = 
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
The terrestrial planets are those that are similar to Earth. In Laint terra means Earth and Earth is Tierra.
The terrestrial planets have solid surface made up of rocks and metals.
There are four terrestrial planet in our planetary (solar) system: Mercury, Venus, Earth and Mars.
You can verify the sizes of those planets in many places.
Earth is the largest of the terrestrial planets.
The speed with which Jennifer climb up the tree is 0.45 m/s
The distance is 10m
Time is 22 seconds
Required speed is 10/22=0.45 m/s
- Distance is the total length travelled by an object.
- Speed is distance upon time.
- It is a scalar quantity and doesn't has magnitude and direction.
- Distance traveled is the total length of the path traveled between two positions
- Distance is the total movement of an object without any regard to direction.

Answer:
Explanation:
What we are basically looking for here is how long it takes the first stone to hit the water. We have everything we need to figure that out. We will use the equation
Δx = . Filling in, we will solve for t, the time is takes the first stone to hit the water (which is the same for both since they both hit the water at the same time):
which is a quadratic that we will have to factor. Get it into standard form, setting it equal to 0:
and factor to get that
t = 3.2 s and t = -2.8 s
Since time can't ever be negative, it takes 3.2 s for the stones to hit the water.
