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
