Question 880287
Jordan's running speed is three times his walking speed. 
He runs for 5 minutes and then walks for 3 minutes,
covering a total distance of 2070 metres. 
What is his walking speed?
***
let x=Jordan's walking speed
3x=his running speed
travel time*speed=distance
..
5*3x+3x=2070
18x=2070
x=115 m/3min=33.33 (m/min)
Jordan's walking speed=33.33(m/min)
