Answer:
57 mph
Step-by-step explanation:
Let b represent Bob's speed on the trip. Then his time is ...
time = distance/speed
Bob's time = 230/b
Then John's speed is b+8, and his time is ...
John's time = 230/(b+8)
The difference of their times is 1/2 hour:
Bob's time - John's time = 1/2
230/b -230/(b+8) = 1/2 . . . substitute the expressions for time
460(b+8 -b) = b(b+8) . . . . . multiply by 2b(b+8)
b^2 +8b -3680 = 0 . . . . . . .put in standard form
(b +4)^2 -3696 = 0 . . . . . . . add 16-16 to complete the square
b = -4 +√3696 ≈ 56.795 . . . solve for positive b
Bob's drove about 57 mph on the trip.
Answer:
1000 times
Step-by-step explanation:
To find out how many times 0.1 can fit into 100, we can just divide 100 by 0.1.
But, we first find out how many times can 1 fit into 100.
No. of times 1 fit into 100 = 100 / 1 = 100 times
Now we know 1 is 10 times of 0.1, so we multiply the above by 10,
so 100 * 10 = 1000 times.
Therefore 0.1 can fit into 100 a 1000 times.
