Quizz time XVII Look Up !
a supernova has push three asteroid in the same path. Asteroid A speed is 114321 m/s Asteroid B is 60000 m/s Asteroid C is 5679 m/s. Asteroid A is behind the B with distance 14883954000 m Asteroid B is behind the C with distance 14878521900 m Question : If Nasa get that data in April 14, at 21.46 1. will A hit B first or will B hit C first ? 2. when the impact happen ?

B hits C first (Relative speed)
April 18
1 51 am
14878521900 /(60000-5679)=273900
273900/(3600*24)=3.17 days later
0.17*24=4.08 hrs
0.08 hrs ~ 5 mins

my previous Quizz

the answer is 30
wait let me type the equation
+ 14
2p + 5e +7s = 30 | *3| 6p +15e + 21s = 90
3p - 6e+5s = 15 |*2 | 6p -12e +10s = 30 // 6p = 12e - 10s + 30 ......(1)
_______________ __
27e + 11s = 60 .......(2)
39e + 1s > 6p
39e + 1s > 12e - 10s +30 //the first equation
27e + 11s > 30 // substract both side with (12e-10s)
60 > 30 // the second equation
now 60 - 30 is 30
hope my explanation is clear
ps i am using web app, so forgive if it is look mess on phone.

@Ulisses Cruz
i am running out idea, now.
actually there are many, but some science concept involved, like physic, chemistry, geometry, inflation, carbon dated fossil, etc. it is hard to find interesting quizz involving only pure calculation.
if i have one, i will post it.

1. B will hit C first. Smaller distance to time ratio.
2. Argh!

Relative speed A,B 54321 m/s
Relative speed B,C 54321 m/s
Since distance of B to C is less hence B hits C first.
