Answer:
13km
Step-by-step explanation:
Given data
Time= 8 days
Speed= 2 1/6 kilometers per day = 13/6 kilometers per day
Distance= ??
We know that
Speed= distance/time
therefore, Distance= speed*time
substitute
Distance= 13/6*8
Distance= 104/8
Distance= 13 km
Hence the crew did 13km
You have to collect like terms that means group the numbers that have the same variables
2-1, 3-2, 4-3, 1*1, 1/7, any number of expressions fit the bill here.
That would be 8. first parenthesis, then multiply, then subtract.
