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

Let’s solve for “a” and “s”.

a = 927 - 45s
a = 792 - 36s

927 - 45s = 792 - 36s
927 - 792 = 45s - 36s
135 = 9s
s = 15
a = 927 - (45 x 15) = 252
