96. mph
mph means miles per hour and is a unit used to measure speed. It expresses how many miles a vehicle or other moving object would travel in one hour if it maintained the same speed.
For example, a speed of 50 mph means travelling at a rate of 50 miles per hour. One mile per hour is approximately 1.61 km/h, so speeds expressed in mph and km/h have different numerical values.
