show the velocity y of each car at time t. Car A reaches a maximum velocity of 140 km/hr. 2) (3 points) Two cars traveled in the same direction along a straight road. The graph below 140 1 Car A V (km/hr) Car B 70 4 t (hr) (a) Fill in the blanks with approximately how long does each car travelled. Car A travelled for hours; Car B traveled for hours (b) Estimate car B's maximum velocity (c) Fill in the blanks with approximately how far does each car travelled Car A travelled KM; Car B travelled KM 3) e* dx using 5 sub-intervals of equal width and the right endpoint of each (2 points) Estimate interval. Work and give your answer accurate to three decimal places. Show your work.
