If you are driving 65 mi/h, how many feet per second are you driving?

65 x 5280 / 3600 ft/s
95.3 ft / s
OPTION C

1 mile = 5280 feet
mph = mph * 5280/3600 = ft/s

65 mph
= 65 x 5280/3600
= 343200/3600
= 95.333333333...... ft/s
≈ 95.3 ft/s
(answer C)

= (65 * 5,280)/(60 * 60)
= 343,200/3,600
= 95 1/3

Answer: C) 95 1/3 feet per second

Answer c.

60sec. = 1min.
60min. = 1hr.
→
1hr. = 60*60 = 3,600sec.

1mile = 1760yds.
1yd. = 3 feet.
→
65miles * 1760 * 3 =343,200 ft

ft./Sec = 343,000 / 3,600
ft./Sec = 95∙333...ft. / Sec.

C) about 95.3 ft/s

60 mph = 88 fps exactly (a convenient conversion to remember), so out of the list, 95.3 ft/s is the only reasonable choice.

So, 1 mph = 1.46666667 feet / second
So, 65 mph = 95.3feet/second approximately.
