Answer:
94 or 95
Step-by-step explanation:
91 + 95 + 87 + 83 = 356
356/4 =89
average so far is 89
356 + 94 = 450
450/5 = 90
356 + 95 = 451
451/5= 90.2
215° because when you add multiples of 360 until you get an angle in the desired range.
Answer:
752.8 miles
Step-by-step explanation:
First we need to calculate the time it takes for them to meet
we add the speeds multiplied by the time (substracting the 4 hours difference for the second train) and it would equal the total distance
80 mi/h× T + 68 mi/h× ( T-4h) = 1121 mi
80 mi/h × T + 68 mi/h× T - 68 mi/h × 4 mi = 1121 mi
148 mi/h T = 1121 mi + 272 mi
T = 1393 mi / 148 mi / h = 9.41 h
then we just multiply the speed of the first train times the number of hours and it gives us the distance it traveled
9.41 h * 80 mi / h = 752.8 mi
