Question

(d) Meena, Beena and Leena are climbing the
steps to the hill top. Meena is at step s, Beena
is 8 steps ahead and Leena 7 steps behind.
Where are Beena and Meena? The total number
of steps to the hill top is 10 less than 4 times
what Meena has reached. Express the total,
number of steps using s.
​

Answer 1

Answer:

4s-10

Step-by-step explanation:

Step at which Beena is = (step at which Meena is) + 8 = S + 8

Step at which Leena is = (steps at which Meena is) – 7 = S = 7

Total steps = 4 × (step at which meena is) – 7 = S – 7

Total steps = 4 × (steps at which Meena is ) – 10 = 4s – 10
