Answer:

  B. 148 miles

Step-by-step explanation:

The rate at which their separation increases is the sum of the two speeds:

  32 mph +42 mph = 74 mi/h

The distance after 2 hours is ...

  separation distance = (separation speed) × time

  = (74 mi/h) × (2 h) = 148 mi

Maria and Ming will be 148 miles apart after 2 hours.
