- Manila and General Santos are about 1000 miles apart. A car leaves Manila to General Santos at the same time as a train leaves General Santos for Manila. The train is 50 mph faster than the car. Find the speed of the car if it takes 5 hours until the train and car meet.arrow_forwardAn engineer is designing a runway for an airport. Several planes will use the runway and the engineer must design it so that it is long enough for the largest planes to become airborne before the runway ends.

- You are driving your car downtown from the beach, but you realize that you need to stop for food. You'd like to stop at the in and out on Jefferson Dr because you think they make the best hoagies in town. You start by driving west on Jefferson Dr at a speed of 18.0 m/s. After 6 minutes, you turn left on Washington st. You get stuck behind someone who isn't in as much of a hurry as you are, and so you slow your speed to 14.3 m/s and continue driving to the south on Washington for another 11 minutes. When you get to Jefferson, you are glad to be away from that slowpoke. You turn right and speed up to a speed of 26 m/s for 13 minutes on your way to the In & Out. At this point, how far (in meters) are you from your starting point at the beach?
