loan



the time it took u to type all that you could have answered them yourself! dont be so lazy|||sorry, TMI for me....|||1. a



2. b



3. time=velocity/distance=52/128=0.406hours



4. 40/231=0.173hours



5. a=1/2bh



242=1/2*11*h



h=44cm



6. perimeter=2(l+b)



162.2=2(32.9+b)



b=48.2cm



7. 26=2(5.5+b)



b=7.5



8. 8.33=2(l+3.5)



l=0.665



9. a=1/2bh



18=1/2*12*h



h=3



10. 32=2(9+b)



b=7m



11.240/64=3.75hrs



12. 2165/6.5=333.07mph



13. 2164.5/37=58.5mph



14. c=(F-32)5/9=(68-32)5/9=20 degree c



15. in 3 hrs jogger runs 3*13=39kms



distance travelled by cycle rider=39+36=75kms



speed =75/3=25kmph



16.0.12x+(4000-x)*0.15=1068



12x+60000-15x=53400



-3x=--6600



x=2200



he invested 2200 @12% and1800 @15%



17.1800



18. let the distance be x



time taken by plane=time taken by car+8.8



x/300=x/60+8.8



solving for x we get x=660miles



20. headstart for the Ford=24km



relative speed ofthe honda=15kph



time taken to catch up=24/15=1hr 36 min=1.6hrs
