Chuck and Dana agree to meet in Chicago for the weekend. Chuck travels 104 miles in the same time that Dana travels 96 miles. If

Yanka [14]

Answer: Chuck's travel at a rate of 52mph

Step-by-step explanation:

For Chuck's trip:

D=RT

104= (R+4)T

T= 104 / (R+4)

For Dana's trip:

96 = RT

T= 96/R

Set both equation for Chuck's and Dana together

104/(R+4) =96/R

Then we cross multiply

96(R+4) = 104R

96R + 384 = 104R

104R - 96R = 384

8R = 384

To get R, divide both side by 8

8R/8 = 384/8

R= 48mph

This means Dana's speed is 48mph

Chuck's speed will be: 48mph+4mph = 52mph

One container holds 1 7/8 quarts of water and A second container holds 5 3/4 quarts of water how many more quarts of water does

BartSMP [9]

$5 \frac{3}{4} -1 \frac{7}{8} = \frac{23}{4} - \frac{15}{8} = \frac{46}{8} - \frac{15}{8} = \frac{46-15}{8} = \frac{31}{8} = \boxed {3 \frac{7}{8} }$
