Problem 3E

Trip Home?. You normally drive on the freeway between San Diego and Los Angeles at an average speed of 105 km/h (65 mi/h), and the trip takes 2 h and 20 min. On a Friday afternoon, however, heavy traffic slows you down and you drive the same distance at an average speed of only 70 km/h ( 43 mi/h). How much longer does the trip take?

Step-by-Step Solution:
Step 1 of 3

Solution 3E Consider 2 hrs 20 min = 2.35 hrs. Distance=speed*time =105 km/hr 2.35 hrs * =246.75 km. Time =distance/speed =246.75 km/(70 km/hr) =3.525 hrs. =3 hour 32 min. =3 hours 32 min 2 hour 20 min = 1 hours 12 min. Hence The trip takes time of 1 hours 12 min.
