Question

Steve and Carl are driving from Scranton to Bridgeport, a distance of 180 miles. If their speed averages 60 miles an hour, how long will it take them to get there

Answer 1

The answer is B

every hour, Steve and Carl cover 60 miles

if they need to cover 180 miles it will take them 3 hours

you can set up a proportion

60/1=180x where x is the amount of hours Steve and Carl will drive to cover 180 miles.

proportion simplifies to this:

60x=180

isolate the varible

60x/60=180/60

x=3

Answer 2

Time = (distance) / (speed)

Time = (180 miles) / (60 mi/hr)

Time = (180/60) (mi-hr/mi)

Time = 3 hours
