Question

Michelle and Themba are travelling from Cape Town to Johannesburg by car. They travel 39km in 18 minutes and continue at a constant speed . How far will they have travelled in 1 hour 24 minutes?​

Answer 1

182 km

Explanation:

They travel 39 km in 18 minutes we want to figure out how much kilometers they travel in 1 minute. What you can do is 39 km / 18 minutes and that gives you 2.16667 km in 1 minute but you want to figure out how much it is for 1 hour and 24 minutes. To do this we need to figure out how many minutes there are in 1 hour and 24 mins, but with prior knowledge we know 1 hour has 60 minutes and 60+24 is 84. We then do 84 times 2.16667 and that gives you 182 km in 1 hour and 24 minutes.
