Two Trains Start From Same Place At Same Time At Right Angles To Each

1.	Two Trains Start From Same Place At Same Time At Right Angles To Each Other. Their Speeds Are 36km/hr And 48km/hr Respectively. After 30 Seconds The Distance Between Them Will Be ?
Answer» Using pythagarous THEOREM, DISTANCE TRAVELLED by first train = 36x5/18x30 = 300m distance travelled by second train = 48x5/18x30 = 400M so distance between them =v( 90000 + 160000) = v250000 = 500mts. Using pythagarous theorem, distance travelled by first train = 36x5/18x30 = 300m distance travelled by second train = 48x5/18x30 = 400m so distance between them =v( 90000 + 160000) = v250000 = 500mts.

Using pythagarous THEOREM,

DISTANCE TRAVELLED by first train = 36x5/18x30 = 300m

distance travelled by second train = 48x5/18x30 = 400M

so distance between them =v( 90000 + 160000) = v250000 = 500mts.

Using pythagarous theorem,

distance travelled by first train = 36x5/18x30 = 300m

distance travelled by second train = 48x5/18x30 = 400m

so distance between them =v( 90000 + 160000) = v250000 = 500mts.
