Acar traveling at constant speed traveled 262.5 miles in 3 1⁄2 hours. what was the car's speed?

Just divide 262.5 and 3 1/2.

262.5 / 3.5 = 75

So the car's speed was 75 miles per hour.

When at a constant speed V, you travel a distance D in a time T defined by D=V*T

Hence V=D/T=262.5/(3+1/2)=75

The car's speed is 75mph

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
