A A motorist is travelling at 15 m/s when he sees a child run into the
road. He brakes and the car comes to rest in 0.75 s. Draw a speed-
time graph to show the deceleration, and use your graph to calculate
a) the distance travelled once the brakes are applied
b) the deceleration of the car.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
