Mary rides her horse with a constant speed of 14 miles per hour. How long will she take to travel a distance of 7 miles?

Mary can travel 14 miles in one hour. Half of that (7 miles) will take her a half-hour.

14 miles for 1 hour
so 7 miles for 30 minutes

D = st
t = D/s
t = (7 miles) /(14 miles/hour)
t = 0.5 hours or 30 minutes... answer//

14 miles in 1 hour, so,
7 miles in half an hour, because,
7 is half of 14.
Consider why you posted this very simple question, when it would have been easier to try it yourself.
Is it lack of confidence in your ability or were you a bit lazy.?
Try to engage with maths. You might find that things start to make sense.

Half of that time which is 30 minutes

Here's the correct method
Given 7 miles, start there, then multiply by converters
7 miles (1 hour/14 miles)
the miles top and bottom cancel, leaving hours
= 7/14 hr = 1/2 hour
1/2 hour (60 minures/1 hour) = 30 minutes

half an hr is how long it will take her
- Iggy RockoLv 71 year ago
time = distance/speed
time = 14/7 = 2 hours

Mary's horse will be exhausted before she reaches 7 miles.
- -j.Lv 71 year ago
constant speed = distance / time
14 = 7 / time
14 * time = 7
time = 7/14
time = 0.5, or half an hour.
Hope that helps!
