Question

Marisa hiked 1 3/4 miles and 3/4 hours at that rate how far can she hike in one hour

Answer 1

(1 3/4) / (3/4) = x / 1.....1 3/4 miles to 3/4 hrs = x miles to 1 hr
cross multiply
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = 7/4 * 4/3
x = 28/12
x = 2 1/3 miles in 1 hr <==

Answer 2

Answer:

2.33 miles/hour

Step-by-step explanation:

If Marisa hiked a distance of 1 3/4 miles in a time of 3/4 hours we can determine her speed as miles per hour. Speed is defined as the distance(d) per time(t). Let speed equal to v:

$v=d/t[tex]

We can determine the decimal numbers of the distance and time:

1 3/4 = 7/4 = 1.75 miles

3/4 = 0.75 hours

∴ [tex]v=1.75/0.75=2.33$

Marisa can hike 2.33 miles per hour.
