Her speed was 50 miles per hour.
If you could drive 184 miles in 15 minutes, multiply 184 by 4 (15 minutes is one-quarter of an hour) to get your MPH. In those 15 minutes, your average speed was 736 MPH.
30 minutes is 1/2 hr. If you are travelling at 70mph, the in half an hour you will travel half of 70 which is 35 miles.
48.8 minutes.
50 miles in 60 minutesdivide both by 105 miles in 6 minutes
8 hours 6 minutes @70 mph

51.5 minutes.
It will take 48 minutes to drive 48 miles at the speed of 60mph It will take approximately 41.09 minutes to drive 48 miles at the speed of 70mph
At 30 mph it takes 40 minutes to drive 20 miles.
If you drive 37 miles in 15 minutes then in 1 hour (which is 4 x 15 minutes) you drive 4 x 37 = 148 miles. Your speed is therefore 148mph.
About 19 minutes
30 miles = 60 minutes 3 miles = 6 minutes 18 miles = 36 minutes
By definition, if I drive at 40 miles per hour for one hour (equivalent to 60 minutes) then I have driven for 40 miles; as for the number of miles you drove, I have no idea.
If it takes 60 minutes to drive 15 miles, it would therefore take 4 minutes to drive 1 mile (60/15=4) so 8 minutes to drive 2 miles!
About 6 minutes
You drove 34 miles in 30 minutes at 68mph
25 miles = 60 minutes 5 miles = 12 minutes 15 miles = 36 minutes 1.5 miles = 3.6 minutes 3 minutes 36 seconds
