Answer:
It will take 0.75B hours for the return leg
Step-by-step explanation:
Here, given that the first leg of the trip was for B hours at 3 miles per hour , we want to calculate the number of hours the return leg will take at 4 miles per hour given that it is the same distance.
Mathematically, we know that ;
Distance = speed * time
So the distance taken on the first leg of the trip would be;
Distance = 3 miles per hour * B hours = 3B miles
Now, this distance was traveled on the return leg also.
This means that the time taken here will be;
Time on return leg = distance/speed = 3B/4 = 0.75B hours
Answer: Charlotte finished the word search in 16 minutes.
Step-by-step explanation:
Frank finished the word search in 32 minutes.
Terrence finished a word search in 3/4 the time it took Frank. This means that the time it took Terrence to finish the word search would be
3/4 × 32 = 24 minutes.
Charlotte finished the word search in 2/3 the time it took Terrence. This means that the time it took Charlotte to finish the word search would be
2/3 × 24 = 16 minutes
