30 minutes.

Well if you are driving 40 miles PER hour, it means it takes 1hour to drive 40 miles. So we know how long it would take to drive 40 miles at 40mph, but there is an extra 20. To do this we just use simple halfing. At 40mph, it would take 1HOUR to drive at 40mph, so if we think, oh it would take 30minutes to go 20 miles at 40miles per hour. So your answer is 1 hour 30 minutes. By Elly Goodwin, Year 8

140/40=3,5 3,5 hours = 3:30 hours so 3 hours and a half

1 hour 37 minutes 30 seconds.

40mph

It will take one hour to travel 30 miles.

If your driving at 60 mph. it will take about 10 minutes ten miles. So it will take 30 minutes for 30 miles! :D

it depends on how fast you travel if you're going about 40mph it will take about 15 minutes It will take exactly 15 minutes at a constant speed of 40mph, to work it out divide the speed you are travelling at by 60 to give you the number of miles per minute then multiply by the number of miles: 60/40 = 1.5 x 10 = 15 minutes and for 30mph 60/30 = 2 x 10 = 20 minutes

It will take: 30/40 = 3/4 of an hour

300/ 30=10

To drive 12 miles at a constant speed of 30 miles per hour, it will take about 24 minutes. Because 30 miles per hour is half as fast, it will take twice as long, at a rate of 2 minutes per mile.
