Problema Solution
Nick is walking at 3 mph, and Jessica is jogging at 6 mph. How long after will they be 3 mi apart?
Answer provided by our tutors
we assume they are jogging in the same direction and that they started from the same place at the same time
relative speed is 6-3=3 mph
distance = speed * time
time = distance/speed
3 mi / 3mph = 1 hour
in 1 hour they would be 3 miles apart
