(a)
To find: the average number of feet built per month by the B crew.
(a)
Answer to Problem 60PPS
B also built 176 feet per month
Explanation of Solution
Given information:
The sunshine skyway bridge spans T.B, F. Suppose one crew began building south from St. P, and another crew began building north from B. The two crews met 10560 feet of St. Petersburg approximately 5 years after construction began.
Calculation:
Both crews built half the bridge in the same time. The work on the left shows that in 5 years St. P built exactly half of the bridge.
Therefore B also built 176 feet per month.
(b)
To find: the number of miles of bridge did each crew build.
(b)
Answer to Problem 60PPS
Each crew built 2 miles.
Explanation of Solution
Given information:
The sunshine skyway bridge spans T.B, F. Suppose one crew began building south from St. P, and another crew began building north from B. The two crews met 10560 feet of St. Petersburg approximately 5 years after construction began.
Calculation:
Each crew built is
Hence, Each crew built 2 miles.
(c)
Whether the answer is reasonable.
(c)
Answer to Problem 60PPS
Yes
Explanation of Solution
Given information:
Yes both crews built half the bridge and the bridge is 4 miles therefore each crew built 2 miles.
