You are driving above the speed limit.    You see a child standing right in front of you at the

swerve out of the way, so, at what speed do you crash into their body?

Speeding....
  You are driving above the speed limit of 70mph.       You see a child standing right in front
  of you at the distance you could safely stop in, if you had been driving at 70mph.

  You can not swerve out of the way, so at what speed do you crash into their body?

  At 70 mph your save stopping distance is 315ft (in good conditions)
