Answer:
<h2>a) Average velocity = 1.25 m/s to the right</h2><h2>b) Average speed = 3.75 m/s</h2>
Step-by-step explanation:
A woodchuck runs 20 m to the right in 5 s, then turns and runs 10 m to the left in 3 s.
Total displacement = 20 - 10 = 10 m to the right
Total time = 5+3 = 8 s
Total distance = 20 + 10 = 30 m
a) We have
Total displacement = Average velocity x Time
10 = Average velocity x 8
Average velocity = 1.25 m/s to the right
b)We have
Total distance = Average speed x Time
30 = Average speed x 8
Average speed = 3.75 m/s
A/b=c
times both sides by b
A=bc
divide both sides by c
A/c=b
b=A/c
Answer:
$9.86
Step-by-step explanation:
Frist you read the problem and you see that she pays $1.89 for one drink
so you write down $1.89
then 3 cookies for $0.99 so you multiply $0.99 by 3 and you get $2.97
so you write down $2.97
next 2 slices of pizza for $2.50 so you multiply 2 by $2.50 and you get $5.00
so you write that down
lastly you and the answers you wrote down and you get $9.86
Maya payed $9.86 for her order.
