1. Investigators determined the speed at the time of an accident to be 65 mph and the road
2 answers:
Answer:
Calculate the skid speed by multiplying the drag factor times the braking efficiency times the skid distance times 30 and taking the square root of the result. For example, if the car skidded 120.5 feet on a road with a drag factor of 0.5 and left four skid marks, the car was going about 42.51 mph.
Step-by-step explanation:
Answer:
Solution given:
65mph
divide the speed value by 2.237
65/2.237=29.05m/s
So
speed =29.05 m/s
now we have
.speed =~30 d (0.5)
29.05/30=0.5d
d=0.96855/0.5
d=1.93
So
the length of the skid marks to be is 2 m.

Answer:
There were 423 adult tickets sold.
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 65 = the number of student tickets sold
x + x + 65 = 715
2x = 715
x = 357.5
x + 65 = 422.5 (round up)
