To a man walking due east at the rate of `2kmh^(-1)`, rain appears to fall vertically. When he increases his speed to `4kmh^(-1)`, its appears to meet him at an angle of `45^(@)`. Find the real direction and speed of rain.

To a man walking at the rate of 3 km//h the rain appear to fall vertically downwards. When he increases his speed 6 km//h it appears to meet him at an angle of 45^@ with vertically. Find the speed of rain.

To a man walking at the rate of 3 km//h the rain appear to fall vertically downwards. When he increases his speed 6 km//h it appears to meet him at an angle of 45^@ with vertically. Find the speed of rain.

To a man walking at the rate of 3 kmlh the rain appears to fall vertically. When he increases his speed to 6 kmlh it appears to meet him at an angle of 45° with vertical. Find the angle made by the velocity of rain with the vertical and its value.

To a man walking at the rate of 4 km/h the rain appears to fall vertically. When he increases his speed 8 km/h it appears to meet him at an angle of 45 with vertical. Find the angle made by the velocity of rain with the vertical and its value.
