Linda goes for a run every day after school, but she likes to make some workouts easier than others. On Monday, Linda ran 3.5 miles in 35 minutes. On Tuesday, she ran 3 miles in 40 minutes. On which day did Linda run at a faster pace?

Linda ran at a faster pace on Monday with a speed of 6 miles/hour

Step-by-step explanation:

Rate or Speed = Distance/Time

On Monday, Linda ran 3.5 miles in 35 minutes.

Converting 35 minutes to hours

60 minutes = 1 hour

35 minutes = x

x = 35/60

x = 0.5833333333 hour

Rate or speed = 3.5miles/0.5833333333 hour

= 6 miles/hour

On Tuesday, she ran 3 miles in 40 minutes.

Converting 40 minutes to hours

60 minutes = 1 hour

40 minutes = x

x = 40/60

x = 0.6666666667 hour

Rate or speed = 3miles/0.6666666667 hour

= 4.5 miles/hour

Linda ran at a faster pace on Monday with a speed of 6 miles/hour

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
