One and fifty onehundredths
Answer:
6
Step-by-step explanation:
100/4 = 25%
24/4 = 6
The travel rates are :
- With traffic = 40 mph
- Without traffic = 60 mph
Recall :
Distance = speed × time
With traffic :
Time taken = 3 hours
Average speed = d
Distance = 3 × d = 3d ---(1)
Without traffic :
Time taken = 2 hours
Average Speed = 20 + d
Distance = 2(20 + d) - - - (2)
Equating (1) and (2)
3d = 2(20 + d)
3d = 40 + 2d
3d - 2d = 40
d = 40
The rates for each half :
With traffic = 40 mph
Without traffic = 40 + 20 = 60 mph
