Final answer:
To convert 2.50 miles an hour to inches a second, multiply the number of miles by 63,360 inches/mile and then divide by 3,600 seconds/hour, resulting in 44 inches per second.
Step-by-step explanation:
To convert 2.50 miles an hour to inches a second, we need to know the conversion factors between miles and inches and between hours and seconds. There are 63,360 inches in a mile (1 mile = 63,360 inches), and there are 3,600 seconds in an hour (1 hour = 3,600 seconds).
First, we convert miles to inches by multiplying 2.50 miles by 63,360 inches/mile:
2.50 miles × 63,360 inches/mile = 158,400 inches/hour
Next, we convert hours to seconds by dividing by the number of seconds in an hour:
158,400 inches/hour ÷ 3,600 seconds/hour = 44 inches/second
So, 2.50 miles an hour is equivalent to 44 inches per second.
