if the brakes of an automobile are applied from 70km/h to 35km/h, how many meters does the car travel during this deceleration?

**Math**

Sin n = 4 / 5. Remember that the formula for sin would be Opposite / Hypotenuse. So: Sin n = Opposite / Hypotenuse = 4 / 5 Sine n = Opposite / 25 = 4 / 5 5 Opposite = 100 5 / 5 Opposite = 100 / 5 Opposite = 20. Now what we do is use Pythagorean Theorem to find the length of th...

I doubt it. Set 3 and 5 into a fraction, like t / 3 + t / 5 = 1. Multiply the denominator, to give you 15. You'll be left with 5t + 3t = 15 8t = 15 8t / 8 = 15 / 8 t = 1.875 = 1.9 min., or 1 min. and 55 seconds
