for a race a distance of 224 meters can be covered by p in 7 seconds and q in 32 seconds . by what distance does p defeat q eventually ?
"explanation : this is a simple speed time problem . given conditions : = > speed of p = 224 / 7 = 32 m / s = > speed of q = 224 / 32 = 7 m / s = > difference in time taken = 25 seconds therefore , distance covered by p in that time = 32 m / s x 25 seconds = 800 metres answer : a"
subtract(224, multiply(7, speed(224, 32)))
