A train travels 33.6 km in 50 minutes. Find the speed of the train in m/s​

time = 50*60 = 3000 seconds.

distance in metres = 9.3.

therefore speed = 9.3/3000 = 0.0031 m/s

Step-by-step explanation:

33.6km in m is 33600m, 50mns in sec is 50×60=3000s

So the speed is S=33600/3000

S=11.2m/s

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
