Answer:
10 rounds.
Step-by-step explanation:
Let x represent number of rounds around the field.
We have been given that the distance around our playing field is 300 meters long. So distance covered in x rounds would be meters.
We are also told that your coach wants you to run 3 kilometers. Let us convert 3 km in meters.
1 km = 1000 m
3 km = 3*1000 m = 3000 m
Now, we will equate total distance covered in x rounds by 3000 as:
Therefore, you need to run 10 times around the field.
Answer:
for the 1st one the answer is x= 3 y=1 and the second one is x= 5 and y = 3 and 1/3
Step-by-step explanation: so basically for the first one -5 times x which is 3 is -15 right? and then 5 times y which is 1 is 5 right so -15 plus 5 = -10
second one is x = 5 and y = 3 and 1/3 because 5*x which is 5 is = to 15 right? and then 3 times y which is equal to 3 and 1/3 is equal to 10 which when you do 15-10 in pretty sure it equals 5 correct me if im wrong
Hope this helps xD ;)
Answer:
Step-by-step explanation:
Let x m/h be the speed of first bus.
Then speed of second bus=x-13 m/h
fist covers covers distance=3x
second covers the distance=3(x-13)=3x-39
again 3x+(3x-39)=339
6x=339+39=378
x=378/6=63
so speed of first bus=63 m/h
speed of second bus=63-13=50 m/h
