Step-by-step explanation:

Answer 2

Answer:  6 & 1/2

This is a mixed number with 6 as the whole part and 1/2 as the fractional part.

Your teacher may want you to enter the answer without the ampersand symbol. If that's the case, then you would type in 6 1/2.

=============================================================

Work Shown:

1/4 = 0.25

3 & 1/4 = 3 + 1/4 = 3 + 0.25 = 3.25

1/2 = 0.5

He runs 3.25 miles in 0.5 of an hour

d = distance = 3.25 miles

t = time = 0.5 hour

r = unknown rate or speed in miles per hour (mph)

------------

distance = rate*time

d = r*t

3.25 = r*0.5

3.25 = 0.5r

0.5r = 3.25

r = 3.25/0.5 .......... divide both sides by 0.5

r = 6.5

r = 6 + 0.5

r = 6 + 1/2

r = 6 & 1/2

His rate is 6 & 1/2 mph
