How it’s solved

Worked on the example above, step by step — follow along and you can do it on paper next time, no tool required.

Time equals distance divided by speed — the faster you go, the less time the same distance takes.
Divide distance by speed
150 ÷ 60 = 2.5 hours
Turn the whole answer into minutes, then split it into hours and minutes
2.5 × 60 = 150 minutes = 2h 30m
