Problema Solution
Car A travels 2 miles at 48 mph. How long does it take him to arrive at his destination
Car B leaves 3 minutes after car A, travels the same distance as car A, in the same time as car A. How fast must car B drive to arrive at the same time as car A
Answer provided by our tutors
let
v1 = 48 mph the speed of car A
t1 = the time of car A
d = 2 miles the distance traveled
v2 = the speed of car B
t2 = the time of car B
t1 = d/v1
t1 = 2/48
t1 = 1/24 hr
t1 = 60/24 min
t1 = 2.5 min
Car B leaves 3 minutes after car A but car A has already arrived on the spot after 2.5 min so car B will never arrive at the same time as car A.
