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
