Apedestrian left his house and started walking on a straight street at the speed of 5 km/h. in t hours he walked s kilometers. what is the formula for dependence of s on t (t≤5)?

S = 5t

Step-by-step explanation:

Speed of the pedestrian = 5 km/h

It means that distance walked in 1 hour = 5 km

Distance walked in t hours = 5*t km = S

Hence;

Formula for dependence of S on t is .

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
