The rate traveled from Amarillo to Austin by a bus averages 60 miles per hour. The bus arrived in Austin after eight hours of travel. An automobile averages 48 miles per hour. Using the inverse variation relationship, show what the time would be for the automobile to complete the trip. 14.4 hours 12 hours 10 hours

the car would arrive after 10 hr to Austin.

Explanation:

bus average from amarllo to austin = 60 miles per hour

time takne by bus to reach austin = 8 hr

automobile average from amarllo to austin = 60 miles per hour

from the information given in the question:

60 mph - - - 8 h

48 mph - - - x h

By using The inverse variation:

60 : 48 = x : 8

60 * 8 = 48 * x

480 = 48*x

x = 480/48

x = 10 h

the car would arrive after 10 hr to Austin.
