Answer:
Step-by-step explanation:
Len and Faye live 54 miles apart. At the same time, they start biking toward each other on the same road. Len's constant rate is 7 mph and Faye's is 11 mph. How many hours will it take them to meet? [Remember: D = (r)(t)]
Answer – 3 hours
D = (r)(t), Where
‘D’ is the distance covered
‘r’ is the approach rate
‘t’ is the total time spent
Distance covered, ‘D’ = miles
Approach rate, “r” = mph + mph 7+11
r = 18
t is unknown
Solving for t,
D = (r)(t)
54 = 18t
t = 54/18
t = 3 hours
