Answer:
h=78.4
Step-by-step explanation:
2/1.25 = h/49
Cross multiplication
1.25h = 2x49
1.25h=98
h= 78.4
CHECK:
2/1.25 = 1.6
78.4/49=1.6
Subtract $15.98, $7.99, $0.50, and 3.59 from $40.00
Answer:
About 384.3 feet
Step-by-step explanation:
The formula for that is given by,

Where,
S is the speed of the car
d is the distance of skid
f is the drag factor for the road surface
n is breaking efficiency as percentage
Putting the values we get,


feet
So the length of skid marks would be 384.3 feet.
30×4=120 then multiply 75×4=340 then add 120+340=460
