In the formula LaTeX: d=rtd = r t, LaTeX: dd represents distance in miles, LaTeX: rr represents average speed in miles per hour, and LaTeX: tt represents time in hours. What is an automobile's average speed, in miles per hour, if it travels LaTeX: 6060 miles in LaTeX: 1\frac{1}{2}1 1 2 hours? Group of answer choices 30 40 60 90 120

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

pi x^2

step-by-step explanation:

pi times x squared

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
