Answer:
D. 1.08 hours
Step-by-step explanation:
Speed = distance / time
Going to the bike shop
speed = 6 mile/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
6 = 2.5 / t
Cross product
6t = 2.5
Divide both sides by 6
t = 2.5/6
= 0.417 hour
She waited for 30 minutes for the repair, that is 0.5 hour
Going back home
Speed = 15 miles/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
15 = 2.5 / t
Cross product
15t = 2.5
Divide both sides by 15
t = 2.5 / 15
= 0.167 hour
Total time of the entire trip =
0.417 hour + 0.5 hour + 0.167 hour
= 1.084 hour
Approximately 1.08 hour
The correct answer is D. 1.08 hours

Answer:
Volume of the lid is 740in³
Step-by-step explanation:
Kindly find attached rough sketch of the lid
The volume of a triangular prism is expressed as
V= 1/2(a*c*h)
Where
a,is the height of triangular base = 4in
c, triangular base = 31in
h, height of the lid = 12in
Substituting our given data we have
V= 1/2(4*31*12)
V= 1488/2=744in³
To the nearest tenth is 740in³
