Answer to Question #14876 in Mechanics | Relativity for desaray
Question #14876
Simpson drives his car with an average velocity of 48.0 km/hto the east. How long will it take hime to drive 144 km on astraight highway? how much time would he save by increasing hiaverage velocity to 56.0 km/h to the east?
Expert's answer
It will take
T1 = 144/48 = 3 hours
to drive 144 km on a straight highway.
He will save
T = T1 - 144/56 = 3 - 144/56 = 3/7 hour
if he'll increase his average velocity to 56.0 km/h.
T1 = 144/48 = 3 hours
to drive 144 km on a straight highway.
He will save
T = T1 - 144/56 = 3 - 144/56 = 3/7 hour
if he'll increase his average velocity to 56.0 km/h.
