how do you solve this. Recklesss randy drives down the road at 48mi/h. Looking down to send a text to his gf he takes his eyes off the road for 5.4 sec. what is his speed in ft per sec (1 mile=5280ft) and how far does the cr travel in the time it takes to send a text.

The whole problem here is convert units of [miles per hour]
into units of [feet per second].

(48 mile/hour) x (5,280 feet/mile) x (hour/3,600 sec) = 70.4 ft/sec

In 5.4 sec, the car travels (5.4 x 70.4) = 380.16 feet .

That's how far back from the wreck they have to go
to find Randy's missing parts.
