It would be first a reflection across A because the points of the triangle are equidistant from the line as they were before just on the other side of the line.
Then it would be a translation because the triangle still holds the same orientation(I don't know if this is the right word) but is moved to a different spot.
Firstly, you change it to miles per second and then to feet 102miles per hour(60×60s) 102 per 120s Divide 102÷120 =0.85miles per second Convert to feet =4488 feet per second
