There are markers every 1000 feet along the side of the road. While driving, Sonya passes marker 8 at 3:10 P.M. and marker number 20 at 3:14 P.M.

Find Sonya's average speed in feet per minute. Use dimensional analysis to check the reasonableness of your answer.

Asked by HardestTooBeat

Answer (3)

Find the distance Sonya traveled: 20-8=12 12x1000feet=12000feet
Find the time it took Sonya to travel this distance: Starting time: 3:10 Finish time: 3:14 Difference= 4min
Use the speed formula: S=D/T S=12000feet/4min S=3000feet/min

Sonya traveled 12000 feet in 4 minutes, so her average speed is 3000 feet per minute. This calculation is reasonable when checking through dimensional analysis. ;

Sonya's average speed is calculated to be 3000 feet per minute, based on the distance of 12000 feet traveled over 4 minutes. This conversion to miles per hour results in approximately 34.09 miles per hour, which is a reasonable driving speed. The calculations adhere to proper formulas and units to verify accuracy.
