A Boy Is Running At A Speed Of P Km/hr To Cover A Distance Of 1km But Due To The Slippery Ground, His Speed Is Reduced By Q Km/hr(p>q).if The Takes R Hours To Cover The Distance Then? |
|
Answer» Actual SPEED = (P-Q)km/hr , time taken =R HRS Therefore, 1 =(P-Q)R => 1/R =(P-Q). Actual speed = (P-Q)km/hr , time taken =R hrs Distance =(Speed x time) Therefore, 1 =(P-Q)R => 1/R =(P-Q). |
