60 dB sound pressure level is about conversational speech listened in 1 meter distance.
If the speed limit is 50, drive 50. If the speed limit is 60, drive 60 and so on.
The optimum sound level for a human being is around 60-70 decibels for regular conversation and activities. Prolonged exposure to sounds above 85 decibels can be damaging to hearing. It is important to protect your ears from loud noises to prevent hearing loss.

It will take you 11 minutes because at 60/mph you're driving at the rate of 1 mile per minute. (60 miles in 1 hour = 60 miles in 60 minutes.)
The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a close range jet. The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a normal conversation. The above answer is FALSE: The decibel scale is logarithmic and thus a 140 dB sound would be 10^14 above 0 decibel; the 60 dB sound would be 10^6 above 0 decibel. Thus the close range jet is around 10^(14 - 6) = 10^8, or 100,000,000 times the loudness of a normal conversation.
To find out how long it will take to drive 278 miles at 60 mph, divide 278 by 60. The answer is 4.6 hours.
what do ya think mph stands for... miles per hour. it will take one hour to drive 60 miles at 60 mph.
Yes.
