A person driving a car with a speed 72 km/h, suddenly sees a boy crossing the road . Solution: Part - I: Now, the velocity of the vehicle (20 m/s) is greater than the safe velocity (18.59 m/s). Your rate is 24 miles divided by 2 hours, so: r = 24 miles 2 hours = 12 miles per hour. How many should it sell to break even if The average speed is going to be equal to two into 1 80 divided by five. In how many hours will they be 300 kilometres apart? Please submit a new, Q:6. #4, Q:16. One cyclist rides twice as fast as the other. (a) Express the horizontal distance d (in miles) that the plane has own as a function of t. Answer: Since the plane is traveling at a constant speed of 350 mi/h and since distance equals rate times time, we have that d(t) = 350t is the horizontal distance function. Therefore we can substitute 2w for l in the equation for the perimeter giving: p = 2*(2w) + 2w For this problem we are also told the perimeter is 3*13.7 which is 41.1 so we can substitute 41.1 for p . Given, Volume of swimming pool = 3400 cubic feet 5. Gigi's sales from her lemonade stand are represented in the graph. It can be defined by using some of the measures.
