depends, if that was the constant speed at all times uphill and downhill, and the times are both the same. then the average speed would be 15mph

The overall stopping distance would be around 122m (400ft) This is made up of a thinking distance of 24m (79ft) and an actual stopping distance of 98m (321ft). The thinking distance is around 3m for every 10mph of speed and the overall stopping distance is calculated as follows: 2x20 ft at 20mph 2.5x30 ft at 30mph 3x40 ft at 40mph 3.5x50 ft at 50mph 4x60 ft at 60mph 4.5x70 at 70mph 5x80 at 80mph = 400 ft james s
6 is 30 less than 6 times itself. Suppose the number is x. Then 6 times itself is 6x. 30 less than that is 6x - 30 So x = 6x-30 so that 5x = 30 and then x = 6
