Answer:
20(E)
Step-by-step explanation:
Printing press R, S and T are working together at their respective constant rate.
They can do a job for 4 hours.
Let r, s and t be the time for printing press R, S and T to complete the job alone at their respective constant rate.
Rate of printing press R = 1/r
Rate of printing press S = 1/s
Rate of printing press T = 1/t
Rate = job / time
R + S + T = 4
1/r + 1/s + 1/t = 1/4
S + T = 5
1/s + 1/t = 1/5
Substitute 1/s + 1/t = 1/5 in the equation 1/r + 1/s + 1/t = 1/4
1/r + 1/5 = 1/4
1/r = 1/4 - 1/5
1/r = (5 - 4)/ 20
1/r = 1/20
r = 20 hours
It takes the printing press R 20 hours to complete the job alone
The child crawled 18 meters in 823 seconds.
Given:
A child is crawling at a pace of 176 inches every 3.37 minutes.
To find:
The distance covered (in meters) by a child in 823 seconds.
Solution:
Distance covered by a child in 3.37 minutes = 176 inches
Distance covered by a child in a 1 minute =
1 minute = 60 seconds
Distance covered by a child in 60 seconds =
Distance covered by a child in a 1 second:
Distance covered by a child in 823 seconds:
In 1 meter there are 39.37 inches.
The child crawled 18 meters in 823 seconds.
