Ravi cycles 9 km due east from his home and then 12 km due north to reach his school. If he could travel in a straight line directly from home to school, how many kilometres would he travel?

Question

Accepted Answer

15. The east and north legs are perpendicular, so straight distance = √9^2 + 12^2 = √81 + 144 = √225 = 15 km.
