Question

Quizplus · Accepted Answer

To solve problems about travel time: Distance = Rate • Time. We want to solve for time, so we rearrange the equation to isolate that variable. Time = ^Distance/_Rate Then we plug in our values: Time = ^Distance/_Rate = ^{20.4 miles}/_{3 mph} = 6.8 hours Then we multiply the decimal (0.8) by 60 to find the number of minutes: 0.8 • 60 = 48 minutes If they hiked 6 hours and 48 minutes, starting at 9am, they would finish at 3:48pm.
