Problem: how many seconds does sandy take to cover a distance of 600 meters , if sandy runs at a speed of 15 km / hr ?
Rationale: "15 km / hr = 15000 m / 3600 s = ( 150 / 36 ) m / s = ( 25 / 6 ) m / s time = 600 / ( 25 / 6 ) = 144 seconds the answer is c ."
annotated_formula: divide(600, multiply(15, const_0_2778))
