Answer»

Now, speed and time are inversely proportional

∴ (s1)(t1) = d1

And, (s2)(T2) = D2

Also, d2 = 3(d1)

∴ $(\frac{{\LEFT( {s1} \RIGHT)\left( {t1} \right)}}{{\left( {s2} \right)\left( {t2} \right)}} = \frac{1}{3})$

∴ $(t2 = \frac{{3\left( {50} \right)\left( {96} \right)}}{{72}} = 200)$ MINUTES
