where did you get this problem? something doesn't make sense to me.duongthang wrote:how many seconds will it take for a car that is traveling at a constant rate of 45 miles per hour to travel a distance of 22 yards? (1mile=1160 yards)
a, 8
b, 9
c, 10
d, 11
e, 12
1. you typed it wrong for sure or the book did. 1mile = 1760 yards, not 1160.
so it travels 45/60min*1/60sec = 45/(60*60) miles per second.
or 1760*45/(60*60) yards per second
which simplies to 22 yards per second. so the answer should be 1 sec.
correct me if I'm wrong...
