distance = speed x time
distance = 50 x 2.5 = 125 miles
About 2 and a half hours.
In 2 hours you travel 18 miles, so in half the time, 1 hour, you'll travel half the distance, 9 miles. So you've travelled at 9 miles per hour (9mph).
Two and a half hours.
157.5 miles
112.5 miles
If you travel at 60 mph, it would take 2 and a half hours. If you travel at 65 mph, it would take 2 hours and 18 minutes.
Four and a half hours !
1 and a half hours
(13 and 1/3) mph
Travelling at 30 miles per hour for 1.5 hours will give a total distance of 30 x 1.5 = 45 miles.
Half an hour at 1450 mph = 725 miles.
Its about 290 miles from Indianapolis to Nashville. Figure about four and a half hours.
