PROBLEM: Four women (Linda, Lisa, Glenda, and Dee) are married to four men (Tom, Duane, Ron, and Ernie). From the clues, determine who is married to whom: · Ernie is Glenda’s brother

· Tom and Duane are training for a marathon next month

· Glenda and Duane were once engaged, but “broke up” later

· Dee has two brothers, but her husband is an only child

· Linda’s husband broke his leg in a ski accident with Ernie and his wife

Who is married to whom?

How about asking your math teacher for help, instead of going to the internet?  As your math teacher, I think it would be a better idea than having your teacher find your internet post!

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
