x = 100° (using definition of vertical angles)
To solve this problem, we know that the formula for average
speed is:
average speed = total distance travelled / total time
Now let us first calculate for the total distance
travelled. Calculating:
total distance travelled = (70 km / hr) * 2 hr + (63 km /
hr) * 5 hr
total distance travelled = 140 km + 315 km
total distance travelled = 455 km
Now for the total time:
total time = 2 hours + 5 hours
total time = 7 hours
Hence, the average speed is therefore:
average speed = 455 km / 7 hours
<span>average speed = 65 km / hr</span>
14, 14 times 4 Equals 66, which is greater than 52. Hope this helps!
The answer is A because the roller coaster is decreasing in ft.
