Trains Boats and Streams Practice Test 4 with solutions

Let the distance covered by Train A = 45 kmph
Let the distance covered by Train B = 40 kmph
Time = 45 minutes
= $\frac{45}{60}$ = $\frac{3}{4}$ hrs.
Distance covered by Train B = $\frac{3}{4}$ = $\frac{\mathit{x}}{40}$
x = $\frac{3}{4}\times 40$ = 30 kms
Distance covered by Train A = 30 + y kms
Speed = 45 km/hr
Time = 45 minutes = $\frac{45}{60}$ = $\frac{3}{4}$ hrs
$\frac{3}{4}$ = $\frac{30+\mathit{y}}{45}$
$\frac{3}{4}\times 45$ = 30 + y
33.75 - 30 = y
y = 3.75
= 3 km 750 m
