A man walks at a rate of 10 mph. After every ten miles, he rests for 8 minutes. How much time does he take to walk 50 miles?	Choose the correct choice from the following options
A) 300
B) 318
C) 322
D) 324
E) 332

Rationale: "to cover 50 miles the man needs ( time ) = ( distance ) / ( rate ) = 50 / 10 = 5 hours = 300 minutes . he will also rest 4 times ( after 10 , 20 , 30 and 40 miles ) , so total resting time = 4 * 8 = 32 minutes . total time = 300 + 32 = 332 minutes . answer : e ."
