Answer:
Distance of Tunnel is 500 meters + Train travel rate is 20 meters per second = 25 seconds to pass through the tunnel only therefore the outstanding balance of 35 seconds x 20 meters per second =600 meters Train
Step-by-step explanation:
Total of length of train 600 meters and tunnel (500 meters) is 1,200 meters +30 seconds = TR of 20 meters per second
$24.00. 6,000 divided by 500 is 12 times the $2 per 500 is $24
(4,6), Using the midpoint formula which is (( x1 + x2)/2), ((y1+y2)/2)
Answer:
Step-by-step explanation:
If Daniel does 1/9 of the job in one hour
let x = Paul's rate
Paul does 1/x of the job in one hour
They both do the job in 4.95hrs
(1/9)(4.95) + (1/x)(4.95) = job completion
multiply both sides by 9x
(9x)(1/9)(4.95) + (9x)(1/x)(4.95) = 9x(1)
4.95x + 9*4.95 = 9x
4.95x + 44.55 = 9x
9x - 4.95x = 44.55
4.05x = 44.55
x = 44.55/4.05
x = 11 hours i.e time it takes for Paul to pick the 40 bushels alone
you add up to the origin then divide your welcome
