( 5.3 * 10^4 ) ( 4.2*10^3)
Multiply the numbers and add the exponents
(5.3 * 4.2) * 10 ^ (4+3)
22.26 * 10^7
now we have to adjust since more than 1 number is in front of the decimal
2.26 * 10^(7+1)
2.26*10^8
-8 i think? hope this helps!
Base elevation is 1250 ft
rate is 30 per minute 30m
so, h = 1250 - 30m
as an inclusion, 30 ft per minute is also like 0.5 per second like 1250 - 0.5s
1250/30 means it would be about 42 minutes once it touches the ground.
