Problema Solution
A competitive high school swimmer takes 42 seconds to swim 100.0 yards. What is her rate in m/min?
Answer provided by our tutors
1 yd = 0.9144 m
100.0 yd = 100*0.9144 m
100.0 yd = 91.44 m
60 sec = 1 min
1 sec = 1/60 min
42 sec = 42/60 min
The rate in meters per minute is:
v = 91.44/(42/60)
v = 130.63 m/min
