In the sprayer speed calibration, mph equals 120 divided by t, where t is the number of seconds required to travel how many feet?

Explanation:
In sprayer speed calibration, the speed in miles per hour comes from how far you travel in feet and how long it takes in seconds, using unit conversions. The general formula is mph = (distance in feet / time in seconds) × (3600 seconds per hour ÷ 5280 feet per mile). If you measure a distance of 176 feet, that constant (3600/5280) times 176 simplifies to 120, so mph = (176 / t) × (3600/5280) = 120 / t. This means t is the number of seconds required to travel 176 feet. The other distance options wouldn’t produce the 120 / t relationship, so they aren’t correct.
