Problema Solution
jordan is on a train traveling at a speed of 188 mph between two cities 1128 miles apart. If the train has been traveling for an hour, how many more hours is her train ride?
Answer provided by our tutors
Let
v = 188 mph the average speed of the travel
d = 1128 mi the distance traveled
t = the hours left to travel
t + 1 = the total time of the travel
Since average speed = distance/time follows distance = speed*time:
v(t + 1) = d
188(t + 1) = 1128

t = 5 hr
Jordan has 5 more hours of train ride.
