1 and a half times because 10 goes in to 25 two times but 10 can't go into 25 so you will get 5 left and 10 - 5 is 5 and 5 tenth makes a half so the answer is,
1 and a half times
Remark
Writing down the givens for these questions is almost a command. You must know which equation of the big 4 to use. The givens + what you want to find will determine the equation.
Givens
vi = 30.7 km/hr = 30.7 km/hr *[1000m/1km]*[1hr/3600sec] = 8.52m/sec
vf = 120 km/hr = 120 km/hr * [1000 m/1 km]*[1h/3600 sec] = 33.3 m/s
t = 4.9 seconds
d = ???
Formula
d = (vi + vf)*t/2
Solve
d = ( 33.3+8.52 )*4.9/2
d = (41.85333)*4.9/2
d = 205.02/2
d = 102.51 m<<<Answer
Answer:
x = -21.83 or (-21.83, 0)
Step-by-step explanation:
Use the given points to find the slope of the line.
(-9, -7) (13, -19)
Use the slope and one of the given points to solve the point-slope formula
Since you are looking for the x-intercept, set y=0 and solve for x
First, you would convert the time of the record into minutes.
78.27 minutes
Then, you would divide that by 26.2.
I hope that helped :)
