Answer:
9/16 hour
Step-by-step explanation:
If the blue troops hikes 2/3 if a mile every 1/2 hour, and the restrooms are 3/4 mile away from the cabin,
Hence:
2/3 mile = 1/2 hour
3/4 mile = x hour
Cross Multiply
2/3 × x = 3/4 × 1/2
x = 3/4 × 1/2/ 2/3
x = 3/8 ÷ 2/3
x = 3/8 × 3/2
x = 9/16 hour
Therefore it will take the blue troop 9/16 hour to walk from the cabin to the restroom.
