When designing the jumps of a bmx racetrack, the jumps involve a launch ramp and a landing ramp. what are some facts about the placement of these features? check all that apply. there must be at least ten launch ramps in every course. the slope of a launch ramp cannot be too high or too low. the length of a landing ramp must be long enough for riders to recover from the jump, but short enough so they do not lose speed for the next jump. there can only be one landing ramp in every course. the slope of a ramp is found by dividing the height of the ramp by the length of the ramp.

The correct options are

BMX racetracks have jumps made for competition and racing. These ramps and jumps must be made in proper format. The height and slope of the jumps must be good enough to avoid any injury to the rider. A higher jump can cause a higher push to the bicycle and when it hit the ground, the rider may fall down and get hurt. In the same way the slope on both launch and land must be kept smooth and proper to avoid falling of the rider.

uhhh idk u yolo?
