The explorer's running velocity will be 1/3 the velocity of the train, 45/3 = 15.
From those issue statement, the train will a chance to be at the begin of the span The point when those voyagers have run 1/3 of the period of the span. In they run of the much end of the bridge, they will bring run 1/3 of the length of the span when those prepare achieves the close to wind. Beginning starting with those 1/3 point, they will make toward those 2/3 perspective At those prepare achieves those span. The prepare will travel the full period of the span in the the long haul it takes those voyagers to run those remaining 1/3. Accordingly the train must travel toward three times the running speed of the voyager. Train = 45 mph, voyagers = 15 mph.
The speed of P&D = 15 mph

Answer:
r=1
Step-by-step explanation:
-7.61 - 4.3r = -8.1r - 3.81
(bring like terms to one side)
-4.3 r = -8.1r -3.81 + 7.61
-4.3r + 8.1 r =-3.81 + 7.61
(consolodate)
3.8r = 3.8
(divide right by # of r)
r = 3.8/3.8
r = 1
Hopefully this will answer your answer trapezoids
