The speeds are 126000 miles per week and 4.2425856e+13 inches per hour

The speed is given as:

Speed of sound travels = 1100 ft/sec,

This means that

Speed = 1100 ft/sec

Convert feet to miles

Speed = (1100/5280) miles /(1/604800) week

Evaluate the quotient

Speed = 126000 miles per week

Also, we have:

Light travels at 186,000 miles/sec

This means that

Speed = 186000 miles/sec

Convert miles to inches

Speed = (186000 * 63360) inches /(1/3600) hour

Evaluate the quotient

Speed = 4.2425856e+13 inches per hour

Hence, the speeds are 126000 miles per week and 4.2425856e+13 inches per hour
