A horse galloped a mile in 2 min 35s. What was its average speed in km/h?

Answer 1

change time to seconds. Then seconds to hours.

change mile to km.

avgspeed=distance/time=1mile/(2min35sec) or
= 1mile/(2min+35sec)*1min/60sec=
=1mile/(2*60+35)sec*3600sec/hr

=1mile*1.609 Km/mile

= 1.609km/155sec*3600sec/hr
=about less than 40km/hr.

Answer 2

37.37
