Question

A man rides 3 km 300 m on a bicycle and then walks 1
3
4
km to his workplace. How would you express the
distance covered by the man in metres?

Answer 1

Step-by-step explanation:

Distance on bicycle = 3 km 300 m

Distance by walking = 134 km

Total Distance = ?

Firstly, lets convert all of them in meters and then add them all.

Cycling : 1 km = 1000 m

              3 km = 3 × 1000 m

                       = 3000 + 300

                       = 3300 meters

Walking : 1 km = 1000 m

               134 km = 134 × 1000 m

                            = 134000 meters

Total distance covered = 3300 + 134000

                                      = 137300 meters

May the answer helps you :)

Answer 2

If a body with position function s (t) moves along a coordinate line without changing direction, we can calculate the total distance it travels from t = a to t = b. If the body changes direction one or more times during the trip, then we need to integrate the body's speed |v (t)| to find the total distance traveled.
