Ambrose and Davis arranged to meet along a path from Vista View to Bathing Point, Ambrose starts at 10 a.m. walking from Vista View toward Bathing Point an average speed of 4 miles per hour. If Davis starts walking the 76 miles from Bathing Point to Vista View at 9 a.m. walking at 6 miles per hour, how far from Vista View will they meet?
A. 48
B. 42
C. 30.4
D. 28
E. 24.4
We have a converging problem in which we can use the following formula:
distance of Ambrose + distance of Davis = total distance = 76
We are given that Ambrose starts walking at 10 a.m. at a rate of 4 mph and that Davis starts walking at 9 a.m. at a rate of 6 mph. Thus, we can let Ambrose’s time = t and Davis’s time = t + 1.
Thus, Davis’s distance = 6(t + 1) = 6t + 6 and Ambrose’s distance = 4t. Plugging this into our original equation, we have:
6t + 6 + 4t = 76
10t + 6 = 76
10t = 70
t = 7
Thus, when the two met, Ambrose had traveled 7 x 4 = 28 miles, so they were 28 miles from Vista View.
