Urgentthe area of a square field is 60025m square.a man cycles along its boundary at 18 km per hour
in how much time will he return at starting point

Answers

Answer 1

Answer: Area of square field = 60025 m

Thus, side = √60025 = 245 m.

Perimeter = 245 * 4 = 980 meters

Speed = 18 kmph = 5m/s

Time = Distance / speed

= 980 / 5

= 196.

Thus, it will take 196 seconds for the man to return at the starting point.

Answer 2

Answer: $Area=60025\ m^2\ \ \ and\ \ \ Area=a^2\n\n\ \ \ \Rightarrow\ \ \ a^2=60025\ m^2 \ \ \Rightarrow\ \ \ a=245\ m\n\n\ \Rightarrow\ \ \ the\ perimeter\ of\ a\ square:\n\n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ P=4a=4\cdot245\ m=980\ m=0.98\ km\n\n Speed=18 (km)/(h) \ \ \ and\ \ \ Speed= \frac{\big{P}}{\big{time}} \n\n18= \frac{\big{0.98}}{\big{time}}\n\n\ \ \ \Rightarrow \ \ \ time= \frac{\big{0.98}}{\big{18}}\ hr=\frac{\big{0.98}}{\big{18}}\ \cdot3660\ s=196\ s=3\ min\ 16\ s\n$

$Ans.\ he\ will\ return \ after\ 3\ minutes\ 16\ seconds.$

You should set up an X and Y table. Make time X and Distance Y. (the table is like a cross: on the left top put x and left top put y. Then under the line list the x and y numbers given in order.) Then find the "slope" which is y/x (rise over run) then you get the increase rate of 45 mph. The relation between them would be D=45t

Answers

The quotient of dividing the given fractions is 20/9.

Given that, 1 7/9=16/9 and 4/5.

From the given fractions we need to divide 16/9 by 4/5.

How to divide the fractions?

A fraction represents a part of a whole or, more generally, any number of equal parts.

The first step to dividingfractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Now, 16/9÷4/5

Change ÷ to × and reciprocate 4/5 to 5/4.

Then, 16/9÷4/5=16/9×5/4=20/9

Therefore, the quotient of the given fraction is 20/9.
