The truck travels 80 km in 35 min

We know that :

35 min = 35/60 hr

           = 7/12 hr

Speed = distance / time

==> Speed ( in km/hr ) = 80 km / 7/12 hr

                                     = ( 80 × `12 ) / 7

                                     = 960 / 7

                                     = 137.1428 approx.

Speed = distance / time

80 km = 80,000 m

==> Speed ( in m/s ) = 80,000 m / ( 35× 60 )s

                                  = 80,000 m / 2100 s

                                  = 38.09523 approx.


Hope it helps :)
