Answer:
Total number of horses used = 16
Step-by-step explanation:
Two pony express riders each rode part of a 176 mile trip. Each rider rode the same number of miles.
They changed horses every 11 miles.
Total number of horses = Number of horses used by each pony express rider x Number of pony express rider
Total number of horses used = 8 x 2 = 16
Total number of horses used = 16
Answer:
3.7m/s^2
Step-by-step explanation:
T is given as 3.27 seconds
L= 1m
we have to find g just put values in given formula
3.27s=2pi(sqrt(1m/g))
3.27s/2pi=(sqrt(1m/g))
0.520s=(sqrt(1m/g))
Taking square on both side to eliminate square root
0.27085s^2=1m/g
Multiply with g on both sides
0.27085 s^2*g=1m
Divide both sides with 0.27085
g=1m/0.27085s^2
g=3.7m/s^2
Answer: t = (3/4)h hours.
Therefore, it takes both of them (3/4)h hours to complete the task.
Step-by-step explanation:
Let
t1 represent the time taken for the one worker to complete a task.
t2 represent the time taken for the second worker to complete a task
And t represent the time taken for both.
t1 = h
t2 = 3h
Let x represent the task.
x = rate × time
r1,r2 and r are the rates at which first, second and both worker works
x = r1(t1). .....1
x = r2(t2). ....2
x = r(t) ....3
And,
r = r1 + r2. ( Rate of both equals sum of rates of the two)
From eqn 1 and 2
r1 = x/t1 = x/h
r2 = x/t2 = x/3h
r = r1 + r2 = x/h + x/3h = 4x/3h
Substituting r = 4x/3h into equation 3
x= r(t)
x = (4x/3h)t
Making t the subject of formula
t = x/(4x/3h)
t = 1/(4/3h)
t = 3h/4
t = (3/4)h hours.
Therefore, it takes both of them (3/4)h hours to complete the task.
