1you type 500 words in 250 minutes find the wpm

2. bus holds 32 students 192 students to use the bus. find the number of students per bus.

could you answer and explain? i haven't learned this yet.

1. wpm = number of words / number of minutes
    so 500/250 = 2wpm

2. if one bus can hold 32 students, and you have 192 of them, divide the amount of students by the number that can fit on one bus
   192/32 = 6 buses

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

The answer is all about the number 4
