Problema Solution
A student ran the 50yd dash in 5.8 sec. At what speed did the student run in miles per hour?
Answer provided by our tutors
1760 yd = 1 mi
1 yd = (1/1760) mi
3600 sec = 1 hr
1 sec = 1/3600 hr
d = 50 yd = 50(1/1760) mi
t = 5.8 sec = 5.8(1/3600) hr
v = d/t the average speed
v = (50(1/1760))/(5.8(1/3600))
by solving we find:
v = 17.63 mph
