Question

A cycler rides 27.0 km in 13 minutes, then 33.0 km in 17 minutes. What is the jogger's average speed in km per minute?

Answer 1

Average speed = 2.01km/min

Step-by-step explanation:

Given the following data

Distance A = 27

Time A = 13 mins

Distance B = 33km

Time B = 17mims

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

`Speed = (distance)/(time)`

For part A

Speed = 27/13

Speed = 2.08km/min

For part B

Speed = 33/17

Speed = 1.94km/min

Average speed = (A + B)/2

Average speed = (2.08 + 1.94)/2

Average speed = 4.02/2

Average speed = 2.01km/min
