We know that the formula for calculating distance is:
distance d = velocity v * time t
Calculating for each interval:
1: 25 km/hr for 4 minutes
d1 = (25 km / 60 min) (4 min) = 1.67 km
2: 50 km/hr for 8 minutes
d2 = (50 km / 60 min) (8 min) = 6.67 km
3: 20 km/hr for 2 minutes
d2 = (20 km / 60 min) (2 min) = 0.67 km
The total distance covered is:
d = d1 + d2 + d3
d = 1.67 + 6.67 + 0.67
d = 9 km
The average speed is:
s = 9 km (1000 m / km) / (14 min * 60 s / min)
s = 10.72 m / s

Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?
b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?
Hence, a) 0.8413, b) 0.9987.
Answer:
You can put this solution
30.24 - 2.24 = $28 just tickets
$28/x = $/person
or
(30.24 - 2.24)/x
Step-by-step explanation:
Answer:
D = 300 m
Step-by-step explanation:
<u><em>Given :</em></u>
Speed = 5 m/s
Time = 1 min = 60 secs
<u><em>Required:</em></u>
Distance = ?
<u><em>Formula :</em></u>
Speed = Distance/Time
<u><em>Solution:</em></u>
Distance = Speed × Time
D = 5 × 60
D = 300 m
