Two cars are travelling on the motorway at a speed of 70 mph. the car behind decides to overtake and at the point where it is level with the front car it is travelling at 100 mph. at this exact moment, both drivers spot an accident up ahead and slam on the breaks.

if the car that was originally in front stops just in time, how fast is the overtaking car travelling when it hits the accident?

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
