Answer:
1650 miles
Step-by-step explanation:
<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs distance = d miles ; rate = 50 mph ; time = d/50 hrs ---------------------- Round-trip DATA: distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs ----------------------------------------------------------- Equation: Roundtrip time - other time = -1/2 hr (2d)/55 - [(d/60)+(d/50)] = -1/2 (2d)/55 - [(110d)/(50*60)] = -1/2 --- 600(2d) - 11[110d] = -16500 1200d - 1210d = -16500 -10d = -16500 distance = 1650 miles Hope this helped :)</span>

The answer is B) 1.9 you need to use Pythagoras where a^2+b^2=c^2, so at 9 o'clock it will make a right angle triangle so the square root of 1.5^2+1.2^2 is 1.92093... rounded it is 1.9
