Answer:
time is 2 hour and 32 min
Explanation:
given data
normal average speed = 105 km/h = (65 mi/h)
trip time takes = 1 h and 50 min = 1.83 hr
average speed with heavy traffic = 75.0 km/h = (47 mi/h )
to find out
How much longer does the trip take
solution
we know that here total distance that is express as
Total distance = Average speed × Total time ..................1
Total distance = 105 × 1.83
Total distance = 192.15 km ( distance between San Diego and Los Angeles )
and when average speed 75 km/h
time will be
time = [tex]\frac{distance}{speed}[/tex]
time = [tex]\frac{192.15}{75}[/tex]
time = 2.56 hr
so time is 2 hour and 32 min
