As Sara rode her bike at 7 mph, how many feet did she travel in 23 seconds? (1 mi = 5280 ft)?

1 mph = (22/15) fps. 7 mph = (7*22/15) fps = 10.2666666 fps. In 23 seconds S travels 23(10.266666) ft = 236.13333 ft = 236.1 ft to nearest tenth of a ft.

3600 sec ________7 x 5280 ft

23 sec ________( 23/3600 ) x (7 x 5280) ft   = 236 • 1 ft

Travels 236 • 1 ft  in  23 sec

Convert the miles to feet and the hour to seconds.

One hour is equal to 3,600 seconds. So multiply 7 by 5,280 to see how many feet she travels per hour, then divide that by 3,600.

As Sara rode her bike at 7 mph, 

how many feet did she travel in 23 seconds? 

1 mi = 5280 ft, 1 hr = 3600 seconds

Sara traveled 236.133 feet in 23 seconds.

7 mph = 7 miles in 1 hour

convert 7 miles to ft.

Convert 1 hour to seconds

Divide the first number by the second, multiply by 23.

236 ft

3600 seconds in an hour

7 mph =>

7 * 5280/3600 ft/sec

23 seconds

7 * 5280 * 23 / 3600 ft =>

7 * 528 * 23 / 360 ft =>

7 * 132 * 23 / 90 =>

7 * 44 * 23 / 30 =>

7 * 22 * 23 / 15 =>

22 * 161 / 15 =>

22 * (150 + 11) / 15 =>

22 * 150/15 + 22 * 11/15 =>

22 * 10  +  11 * (15 + 7) / 15 =>

220  +  11 * 15/15  +  11 * 7/15 =>

220 + 11 * 1  +  77/15 =>

220 + 11 + 75/15 + 2/15 =>

231 + 5 + 2/15 =>

236 + 2/15

2/15 ft = x/12 ft

2/15 = x/12

2 * 12/15 = x

2 * (4/5) = x

1.6 = x

236 ft 1.6 inches

Really?  1 mile = 5280 feet?  Are they 5280 smelly feet?  Wow,and here I thought that 1 mile was 12,000 feet.  (Yes, I am making fun of you..)
