A cyclist travelled east at 15 m/s for 15 seconds, and then he stopped to rest for 10 seconds. Then, he moved west at 2 m/s for 75 seconds. Find the cyclist’s average speed for the whole trip.
Two cars were moving in opposite directions on a road between and . The first car started at point and travelled at 104 km/h, and the second started at point and travelled at 100 km/h. given that the points and are 153 km apart, determine the time and the distance from point at which the two cars met.
