Two bike messengers, Jerry and Susan, ride in opposite directions. Is this government? How much are your pounds worth in U.S dollars? Find the distance it has traveled from time $t=1$ hour, The car drove on one section of the highway for half an hour at a speed of 80 km/h. First, subtract the time spent at the train stops: 2.5 x 4 = 10 minutes. If given a total distance of both persons or trips, put this information in the distance column. Next, you ride 18 miles and travel at a rate of 12 miles . 10 The total distance travelled by a boat 1 hour upstream and 30 minutes downstream in which. Distance, rate and time problems are a standard application of linear equations. Thus, the car would have an average speed of 100 miles / 4 hours = 25 mph.. Two trains A and B leave stations P and Q simultaneously and travel towards Q and P respectively on the same route.
