Ananth ran a 4 km at an average speed of 10 km an hour. If he started his run at 5:00 am, at what time did he finish?

see explanation

Step-by-step explanation:

used formulla: s=d/t

or St =d

or t=d/s.

speed(s) = 10km/hr =2.78m/s

distance(d) = 4 km = 4000m

time(t) = ?

we have,

t= d/s

t = 4000/2.78

t = 1438 s

1438 s =23.96 min = 0.39 hrs

:- ananth finished at 5 hrs 23 min.

hope this will help u..

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
