Answer 1

Answer:

1) 120 km

Step-by-step explanation:

S=D/T.

THEREFORE D=S*T SO

D=80 * 1.5 =120 KM

Answer 2

Answer:

Step-by-step explanation:

1. Distance covered by train =speed*time

  80*1.5=120km

     2. Time taken =distance/speed

                   also speed is given in km/hr so we need to change it m/s

                         by multiplying it with 5/18

=25*5/18=6.94

        =800/6.94=115.2 sec
