Problem: Two cars A and B are 200km apart and they are traveling toward each other at the speeds of 28km/h and 22 km/h respectively. When and where will they meet? 2. If the car A and B in problem 1 start from the same point, going toward the same direction, at what time will they be 18km apart? 3. If B starts at 1:00pm and gives chase starting at 1:15 from the same point as B, when and where will A overtake B? Thank you so much for answering!!
Help...
1) relative speed =28+22=50 they will meet after 200/50=4 hr at a distance of 28*4=112 km from the starting poing or (200-112=88 from the other sid)
2) relative speed now =28-22=6 they will be 18 km apart after 18/6 = 3 hr
