A group of campers and one group leader left a campsite in a canoe. They traveled at an average rate of 10 km/h. Two hours later, the other group leader left the campsite in a
motorboat. He traveled at an average rate of 22 km/h. How long had each boat traveled when
the motorboat caught up with the canoe?

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

inverse operation of addition

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
