QUESTION A car completes a journey in 10 mins. For the first half of the distance the speed was 60 km/h and for the second half the speed was 40 km/h. How far is the journey?
Answer in book is 8 km. I can't get that answer.
I'll show you my efforts but I think I'm wasting time if the question is wrong. How can the first half of the distance be the same as the second half if the speeds are different?
Before I carry on attempting I need to ensure that I've got 10 mins correctly converted to hours.
10 mins = 10/60 hours = 0.16 hours?
Please advise. Thank you
