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

40mph
It will take 20 min to go 20 miles at 60 mph.
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 would take 12 minutes to drive 20 miles at 100 mph.
30 minutes.
20 minutes 60 miles = 1 hour = 60 minutes 10 miles = 10 minutes 20 miles = 20 minutes
20/65 = 18minutes 27.7seconds
20 minutes at 60 mph.
It will take: 20/4 = 5 hours
It will take about 20 minutes to drive the 13.5 miles.
