Answer» n:1) 7.5 m/ sec---> 1000m = 1 km1000m = 1 KM1 m = 1/1000 km----> 1 hr = 60 × 60 = 3600 secs3600 SECONDS = 1 hr3600 seconds = 1 hr1 sec = 1/3600 hrWhile we convert metre to kilometer we have to divide by 1000Seconds to hours we have to divide by 3600__________________________________________________2) 1 m/ secKnowledge booster: # While solving for unit conversion take care where to do division and multiplication for conversionExample : 1 metre to kilometre1000 m = 1 km1 m = 1/1000 kmExample: 10 metre to centimeter1 m = 100 cm10 m = 10 × 100 = 1000 cm______________________________________# While converting smaller unit to larger unit do division and from larger to smaller do multiplicationExample: 5 m to kilometre= 5/1000 = 0.005 kmExample: 50 m to cm= 50 × 100 = 5000 cm_____________________________________# Solve more such unit conversion questions to get good HOLD on it |
