A stairway 10ft high is such that each step accounts for half a foot upward and one-foot forward. What distance will an ant travel if it starts from the ground level to reach the top of the stairway?
Answers
Answer:30 feet
Step-by-step explanation:
The height is = 10 feet
Each of 1/2 feet, therefore there are 20 stairs in total.
ATP,
THERE ARE 20 STEPS WITH 1 FEET FORWARD = 20 FEET
therefore 10 + 20= 30 feet
Answer:
Step-by-step explanation:
The stairway is 10 fit high and each step is only half a foot upwards that means it will take two stairs to make one fit upwards and 20 stairs to cover 10 fit.
The ant also has to go forward. As there are 20 stairs and each stair is one fit forward, we may jump into the conclusion that it will travel 20 fit forward but think the ant has to reach at the 20th stairs after reaching at the 20th stairs it won't travel the length of the 20th stair. That's why it will travel the length of 19 stairs forward.
So the total distance: 10 ft+ 19 ft= 29 ft
