I NEED HELP CONVERTING MATH

Question

Use unit multipliers to convert 208 miles per hour to feet per second. Round your answer to

the nearest hundredth

Answer 1

1 mile = 4 laps around the track around a football field

= 4(440) yards

= 1760 yds, = 3(1760) feet = 5,280 feet

208 miles = 208(5280) feet = 1,098,240 feet

1 hour = 60 minutes= 60(60) = 3.600 seconds

208 mph = 1,098,240 ft per 3600 sec

= 1.09824 x 10^6/3.6 x 10^3 = (1.09824/3.6) x 10^3

= 0.3050666...x 10^3 = 305.0666... ft/sec

208 mph = about 305.07 feet per second

Answer 2

208 mph * 5280 feet/mile * 1 hour/ 60 min * 1 min/60 sec

208*5280/(60*60) = 305.06666.... feet per second

305.06

Answer 3

Hello Caleb

1 mile = 5280 feet and 1 hour = 3600 second;

208mph = 208*5280 feet per hour = 1098240 feet per hour = 1098240/3600 = 305.07 feet per second

hope that helps
