Answer:
7.6m/s
Step-by-step explanation:
Find the time the Olympian swam
Speed=distance/time ⇒⇒Time=distance/speed
Distance=200m , speed= 1.8m/s t= 200/1.8 = 111.11 seconds
Find the speed of the Olympic runner
Distance=200m time = 21.3 sec
s=200/21.3 = 9.4 m/s
Difference in speed= 9.4-1.8= 7.6m/s
This can vary, some shapes have different area formulas, here are some basic formulas I can give you:
Circle: A =
Triangle: A =
Square: A =
Rectangle: A = L*W
I don't know if this is the ans.u2+14-28=0
