ANSWER WELL WITH GOOD EXPLANATION AND IF IT IS GOOD THEN I WILL GIVE AND DONT ANSWER OR POINTS OR I WILL REPORT

Leila is the better runner.

Step-by-step explanation:

Velocity of Leila = (3×3/5)/(7/60) km/h

=15.42( approximately)

Velocity of Maria= (3/5)/(3/60)km/h

=12 km/h

So, as Leila is faster than Maria, she is the better runner.

Hope this helps

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
