Question
A train travels a distance of 300 km with an average speed of 60 km h_1. How much time does it take to cover the distance?
Solution
Speed = `60 "km" "h"^-1`
Distance covered = 300 km
∴ Speed = `"Distance covered"/" Time taken"`
∴ Time taken = `"Distance covered"/" speed"`
= `(300 "km")/(60 "km" "h" ^-1)`= 5h
