Answer 1

1. given,

speed=48km/hr
=48*5/18 = 13.33

Time=45 min

We know,

distance=speed x time
. =13.33 x 45
=599 meter.


2) speed= 50 km/hr

Distance= 175 km

Time= distance/speed
=175/50
=3.5 hr

3) speed=12 km
Distance=8 km
Time=distance/speed
=8/12 =0.6 hr

speed= 45km/hr = 45x 5/18
=12.5 m/s
