Answer:
4 inches per second
Step-by-step explanation:
Speed = distance/time
Given
Distance = 20 feet
12 inches = 1 foot
X inches = 20 feet
X = 20 x 12 = 240 inches
Time = 1 minute = 60 secs
Therefore
Speed = 240/60
= 4 inches per second
Well, 5 tens is equivalent to 50, and 29 ones is equivalent to 29, so 50 + 29 = 79 =)
I hope I helped! =D
