2 miles in 30 minutes means 4 mph.
It's 25 miles per half-hour, and it's also 50 miles per hour.
Speed = 85/2.5 = 34 mph
32 miles per hour. The speed at which the car is travelling is the distance in miles that the car travels per hour. If the car travels 16 miles in 30 minutes it should then travel twice as far in one hour, since one hour is twice as long as 30 minutes (half an hour). So, the car travels 2 * 16 miles per hour, which equals 32 miles per hour.
50 minutes.

260 miles an hour
67,062 miles per hour.
one and a half times 20, ie 30 miles
Just divide distance by time to get speed.30 miles / 1.5 hrs = 20 MPH
55 miles per hour.
1 hour
The faster car travels at 48 miles per hour The slower car travels at 36 miles per hour 48mph - 36mph = 12mph Therefore, the faster car travels 12 miles per hour faster than the slower car. Note that the question refers to the relative speeds of the cars and not the relative distances.
