If you were getting 20% off of a £7.50 admission the new price would be £5.
This is due to the fact that 10% is 0.75
You can get 10% by dividing the number by 10.
10% doubled to get 20% is £1.50
7.50 minus the 20% off, 1.50, would be £5.
x - 6(8) = 132
x = 48 + 132

Sound travels 10200m farther through stone in 17 seconds than through aluminium
Speed of sound in aluminium = 3100 m/s
The speed of sound in stone = 3700 m/s
Time taken = 17 minutes
Distance traveled = Speed x Time
Distance traveled by sound in aluminium in 17 seconds = 3100 x 17
Distance traveled by sound in aluminium in 17 seconds = 52700 m
Distance traveled by sound in stone in 17 seconds = 3700 x 17
Distance traveled by sound in stone in 17 seconds = 62900 m
Difference in the distance traveled = 62900 - 52700
Difference in the distance traveled = 10200 m
Sound travels 10200m farther through stone in 17 seconds than through aluminium
