You walk 2 miles in 1/2 hour. At that rate, how long will it take you to walk 3 miles?

answers:
Philomel say: 2 mi in 1/2 hr = 4 mph. 3 mi = 3/4 hr = 45 min.

Steve say: Direct variation takes the form: y = kx, where k is a numerical constant. In this case x is time and y is distance. So, 2 = k(.5), and k = 4. Therefore, 3 = 4x. And, x(time) = 3/4 hr. or 45 minutes.

Ian H say: You walked 2 miles in 1/2 hour, so if you kept up that rate
3 miles might take half as long again, so that would be 45 minutes.
However, that is a fast rate of 4 miles per hour, and you might slow down,
or even stop to buy a sticky bun or talk to a friend.

Como say: 3/2 x 1/2 = 3/4 hour = 45 min

RR say: You walk 2 miles in 1/2 hour.
Therefore, you walk half that distance in half that time: 1 mile in 1/4 hour
Therefore you walk 3 miles in 3/4 hour

Krishnamurthy say: 3/4 hour

Murzy say: 45 mins

Fred3663 say: That would be 3/4 hour.

Morningfox say: It will take you 1/2 hour, plus onehalf of 1/2 hour.

David say: It is a 1/4 of an hour for each mile and so 3 times 1/4 = 3/4 of an hour

Abe say: 45 minutes

Rain say: 45 minutes

Ocate say: rate = 2 miles / (1/2 hour) = 4 hour / mile
time = 3 miles / 4 miles / hour = 3/4 hour = 45 miles

say: 1 mile in 1/4 hour  15 minutes
2 miles in 2/4 hour  30 minutes
3 miles in 3/4 hour  45 minutes
4 miles in 4/4 hour  60 minutes or 1 hour
So your rate of speed is 4 miles per hour

Jim say: 3/4 hour or 45 minutes
