So you want to make it: total distance (d) = rate (r) × total time (t), solving for r: r = d / t
r = (420mi) / (3h+214h), r = 420mi / 217h
r = 1.935mi/h = 1.94mi/h

Use braces and digits to indicate the set of whole numbers
Sergeeva-Olga [200]

Whole numbers are numbers without decimal points greater than 0.

This means that the following numbers are whole numbers:

1, 9, 10, 67

While the following numbers are not:

-1, 9.0, 1.0, -67

Let W be the set of whole numbers; the set is:

W =\{0,1,2,3,4.....\}

The dots after 4 means the set still continues

<span>Let x be additional food item the homeroom B should collect  to have greater item per student than homeroom A.</span>

(22 +24 + x) / 16 > (30 + 42 + 21) /24

(22 +24 + x) > 3.875 (16)

X > 16
