This is correlation between distance-time-speed that we will use in answering d = vt t = d/v v = d/t d stands for distance, v stands for velocity/speed, t stands for time
First, we should count the distance she took for the first two hours d = vt d = (60)(2) d = 120 For the first two hours, she took 120 miles
Second, calculate the distance for the next two hours d = total distance - first distance d = 210 - 120 d = 90 The remaining distance is 90 miles
Third, calculate the speed for the next 2 hours s = d/t s = 90/2 s = 45 The speed for the last two hours is 45 miles per hour
