The second table shows the frequency of the test times. There are 4 numbers that fall between 50-59, 7 between 60-69, 6, between 70-79 and 3 between 80-89
rt=d
d = 3 km = 3000 m
t=2 hrs. = 7200 seconds
r= x
r= d/t 3000/7200 = 5/12 m/s = 0.416 m/s = 1.5km/h

Answer:
Step-by-step explanation:
1.5 x 4.5 x 4.5 = 30.375
30.375 ÷ 3 = 10.125
10.125= volume of the triangle
3 x 4.5 x 4.5 = 60.75
60.75 = volume of rectangle
60.75 + 10.125 = 70.875
70.875 = total volume
