What’s is it about can you tell me.?
Answer:
Step-by-step explanation:
Because of the power of a power property, which states that 
, where m and n are real numbers, the expression you mentioned can be simplified by applying this property like this: 
Value of angle Y is 180-51
48 miles/4hrs = 12 mph
Increased Speed 12 mph + 8mph = 20 mph
Distance left 108 miles - 48 miles = 60 miles
Time left 60 miles/20 mph = 3 hours
30% is .3 so 20 times .3 is 6 extra miles so 30 plus 6 is 36 miles
