Step-by-step explanation:
1. given distance=250m
time=75sec
speed=distance/time
=250/75=10/3mps
=(10/3)*(18/5)=12kmph
2. speed=72kmph=72*(5/18)=20mps
time=5sec
dis=20*5=100m
3. dis=4/5km=4*1000/5=800m
speed=45kmph=45*(5/18)=25/2
time=800*2/25=1600/25=64
4. 240*5=5x/3
x=240*3=720
5. 40*9=60*x
x=6
6. distance=s*t=(5*5/18)*15*60=25*15*60/18=25*5*60/6=1250
7. average speed=2s1s2/s1+s2
=2*500*700/1200
=5*700/6
=583.66=5831/3
8. d/s1+d/s2=5+48/60=5+12/15=5+4/5=29/5
d(1/s1+1/s2)=29/5
d(1/25+1/4)=29/5
d(29/100)=29/5
d/100=1/5
d=20
9. speed=20/2.5=200/25=8
speed doubles=16
distance/speed= time
t=32/16=2
10. time taken to travel the dstance=10.30 hrs=101/2hrs=21/2 hrs
distance=speed *time=40*21/2=420Km
