Question

A cycle race is a whole number of kilometres (km) long. Its length is 200 km when rounded to the nearest 100 km. The same distance is 150 km when rounded to the nearest 10 km. Write down a possible value for the length, in km, of the race.​

Answer 1

151 - 154 km

Explanation:

when rounded to the hundreds 150 rounded up is 200 . But if you round the number to the nearest 10 and it is 150 then it has to be 150 or above in order for it to go to 100. But for it to be rounded to the nearest 10 of 150 it needs to be less than 155 or else it gets rounded up to 160. So then you get a range of answers from 151 - 154. Most likely it will be 150 km or maybe even 154 km.

Answer 2

Explanation:

150 km ≤ river length < 155 km

its 150
