If you run a 10 kilometer race in 42 minutes 42 seconds, what is your average pace (time per mile in minutes and seconds)? what is your average speed in miles per hour?

Solution:

Average Pace = 0.621371 mile

10 km = 6.21371 mile

42 min 42 sec = 42.7 min

Average pace = minute/mile

42 minutes 42 seconds = 2520 + 42 = 2562 sec

Average pace =

Also, 42 min 42 sec = 0.7116 hour

Average speed =

Hence, the average speed is 8.732 mile/hour

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
