In one hour Dele walks 8km. How long will it take her to walk 14km at the same rate?

Show workings bit by bit

1. 8km in 1 hour = 8km/1 hour

2. 14km/8km/1 hour = 1.75 hours

Did you know?

Did you know that we can use a simple proportion to find out how long it will take Dele to walk 14km, based on the information that in one hour she walks 8km? To solve this problem, let's first set up a proportion: 1 hour / 8 km = x hours / 14 km To find the unknown value, x (representing the time it will take Dele to walk 14km), we can cross-multiply: 8 km * x hours = 1 hour * 14 km Simplifying the equation, we have: 8x = 14 Now, to isolate x, we divide both sides of the equation by 8: x = 14 / 8 x = 1.75 Therefore, it will take Dele approximately 1.75 hours (or 1 hour and 45 minutes) to walk 14km at the same rate as she walks 8km. This method of using proportions can be very helpful in solving various problems involving ratios and rates, offering a quick and effective way to determine unknown values.
