Question 1
A tortoise cycles from the foot of a mountain to its summit at 20 metres per hour and returns at 40 metres per hour. The whole trip takes 3 hours. How long is the mountain route in metres?
Source-intended distance: the one-way mountain route; the full round trip is twice as long. The bilingual source unit discrepancy is documented in the solution.
