Answer:
2.5 meters per second
Step-by-step explanation:
Given,
The speed of Charlotte = 9 km/h
That is, the distance covered in 1 hour = 9 km,
∵ 1 km = 1000 m
So, the distance covered in 1 hour = 9000 m,
∵ 1 hour = 60 minutes and 1 minute = 60 seconds,
⇒ 1 hours = 3600 seconds,
∴ The distance covered in 3600 seconds = 9000 m,
⇒ Distance covered in 1 second =
= 2.5 m,
Hence, his/her speed = 2.5 meters per second
Answer:
7/36
Step-by-step explanation:
1 die has 6 faces
When two dice are rolled, the total number of outcomes
= 6 × 6 = 36
The Probability of having(5) =
(1 & 4), (2 & 3) , ( 3 & 2), (4 & 1)
= 4
The probability of having (10) =
(5 & 5), (4 & 6) , ( 6 & 4)
= 3
The probability that the score on the dice is either 5 or 10.
P(5) + P(10)
= 4/36 + 3/36
= 7/36
