A biker travels 5 feet in 0.5 seconds. At this exact speed, how far will the biker travel in a minute?

Pavel [41]

A minute has 60 seconds, therefore we will deal with seconds now And since we have it that the biker travels 5 feet every 0.5 seconds, lets multiply that by 2 to get the traveled distance per second to make it easier 5*2=10 Finally, multiply 10 feet by 60 seconds(1 minute) = 600 feet
