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 = ^{40,074 km}/_3950km/h = 10.15 hours Then we multiply the decimal (0.15) by 60 to find the number of minutes: 0.15 • 60 = 9 minutes Finally, add the minutes to the hours: 10 hours and 9 minutes
