The east bound train travels at a speed of 95 mile per hour and the west bound train at 75 miles per hour.
Assuming eastbound train will cover distance x then the west bound train will cover distance 272-x .
Therefore, since time taken will be the same then; x/95 = (272-x)/75
= 75x = 95 (272-x)
= 75x = 25840 - 95x
= 170 x= 25840
x = 152 miles
Thus time taken will either be x/95 or (272-x)/75
= 152/95
= 1.6 hours or 1 hour 36 minutes
A catalyst is a substance that alters the reaction and doesn't involve in the reaction.So if the Manganese was a catalyst the mass would not have decreased,it would just continue aletring the reaction until its used up.
The Manganese is not acting as a catalyst

Explanation:
Magnetic field due to a long wire
B = ( μ₀ / 4π ) x 2 I / r ( I is current through the wire )
= (μ₀ Q t ) / ( 2 π r ) [ I = Q t ]
b ) Magnetic field will change through the length of the square shaped loop . So we shall have to take the help of integration to calculate the flux through the loop.
Flux Φ = ∫ B dA
=∫ ( μ₀ / 4π ) x 2 I / r dA
10⁻⁷ x 2 I ∫ a dr/r
2 x 10⁻⁷ x Qt x a [ ln (2.9+1.2) / 1.2 ]
4.6 x 10⁻⁷ x 2.9 x 10⁻² t ln 4.1 / 1.2
16.4 x 10⁻⁹ t
Φ( t ) = 16.4 x 10⁻⁹ t
Induced emf = dΦ( t ) / dt = 16.4 x 10⁻⁹ v
current
16.4 x 10⁻⁹ / 2.5
= 6.56 x 10⁻⁹
