If log 0.317=0.3332 and log 0.318=0.3364 then find log 0.319
log 0.317=0.3332 and log 0.318=0.3364
A box of 150 packets consists of 1kg packets and 2kg packets. Total weight of box is 264kg. How many 2kg packets are there
x= 2 kg Packs
y= 1 kg packs
x + y = 150 .......... Eqn 1
2x + y = 264 .......... Eqn 2
solve the Simultaneous equation;
x = 114
using Eqn 1,
114 + y = 150
so, y = 36
ANS : Number of 2 kg Packs = 114.
My flight takes of at 2am from a place at 18N 10E and landed 10 Hrs later at a place with coordinates 36N70W. What is the local time when my plane landed?
6:00 am b) 6:40am c) 7:40 d) 7:00 e) 8:00
The Answer is 6:40 AM
The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360).
When the flight landed, the time at the starting place is 12 noon (2 AM + 10 hours).
Hence, the time at the destination place is 12 noon - 5:20 hours = 6: 40 AM
A plane moves from 9˚N40˚E to 9˚N40˚W. If the plane starts at 10 am and takes 8 hours to reach the destination, find the local arrival time.
Since it is moving from east to west longitide we need to add both
multiply the ans by 4
convert this min to hours ie, 5hrs 33min
