If you can walk 3 1/3 miles in an hour, how many miles can you walk in 30 minutes, given the

Vedmedyk [2.9K]

Answer:

d = 1.67 miles

Step-by-step explanation:

Given that,

Speed of a person, $s=3\dfrac{1}{3}\ mph$

We need to find how many miles can you walk in 30 minutes, given the same pace.

30 minutes = 0.5 h

$3\dfrac{1}{3}\ mph = \dfrac{10}{3}\ mph$

Speed = distance/time

$d=v\times t\\\\d=\dfrac{10}{3}\ mph\times 0.5\ h\\\\d=1.67\ miles$

So, the person will cover a distance of 1.67 miles
