= Given that the total distance travelled = 810 m, find: a) the value of V.
b) the rate of change of the speed when t = 30. c) the time taken to travel the first 420 m of the journey.

Step-by-step explanation:

= Given that the total distance travelled = 810 m, find:

a) the value of V.

b) the rate of change of the speed when t = 30. c) the time taken to travel the first 420 m of the journey.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
