Un automóvil viajando a 95 km/h logra sobrepasar a un tren de 1.30 km de largo que está viajando en la misma dirección, en un riel paralelo a la carretera. Si la rapidez del tren es 75
km/h, ¿cuánto tiempo le tomó al automóvil sobrepasar al tren y cuánta distancia recorrió en
ese tiempo? (Escriba sus respuestas finales con 2 cifras significativas):
(a) Tiempo que le tomó al automóvil sobrepasar al tren =
min
(b) Distancia que recorrió el automóvil en el tiempo calculado en (a) =
km

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
