Landon rides his bike 178 feet in 8 seconds, find the unit rate

22.25 ft/s

Step-by-step explanation:

Unit rate is distance/time

If he rides his bike 178 ft in 8 sec, unit rate is 178ft/8s = 22.25 ft/s

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
