Answer:
Car A blinks 36 more times than Car B
Step-by-step explanation:
To figure out how many times Car A blinks, you have to divide 60 / 5 which equals 12. Since it blinks 7 times per 5 seconds, you would have to multiply 7 by 12, which equals the answer for the first part, 84 times per minute.
To figure out many times Car B blinks, it's the same way. But this time, you multiply 12 by 4, since it blinks 5 times every 4 seconds. Which in that case is 48 times per minute.
So, 84 - 48 = 36 times more than Car B
Answer:
230.77 seconds or about 3.85 minutes (2 minutes 50.4 seconds)
Step-by-step explanation:
First I will convert the minutes into seconds to make this a little easier.
1:01.71 would just be 61.71 seconds
400/61.71 is her speed for the first race. (speed is distance/time)
That is approximately 6.5 meters per second
time is distance/speed
1500/6.5= 230.769...
I do not know what you need to round to, but Juliette would take 230.769 seconds to run the 1500 meter race.
Hello!
An easy way to find military time that is more than 12 is to subtract 12 from the number. For example, 14:00-12= 2:00 P.M.
In this case 13-12 is 1:00, and 20-12 is 8:00.
This nurse works from 1:00 P.M. to 8:00 P.M., or the afternoon.
I hope this helps!
