Ali walks at a speed of 48 m/min, while Tina walks at a rate of 62 m/min. if they are 1320 m apart and they walk towards each other until they meet. How many minutes would it take?
let the time be t minutes
distance covered by Ali = 48t
distance covered by Tina = 62t
48t + 62t = 1320
solve for t
relative velocity=110m/min
timetomeet=distance/relativeV=1320m/(110m/min)=12 min
To find out how many minutes it would take for Ali and Tina to meet, we can use the concept of relative speed.
Relative speed is the combined speed at which two objects are moving towards each other. In this case, Ali and Tina are walking towards each other, so their relative speed is the sum of their individual speeds:
Relative speed = Ali's speed + Tina's speed
Ali's speed = 48 m/min
Tina's speed = 62 m/min
Relative speed = 48 m/min + 62 m/min
Simplifying, we get:
Relative speed = 110 m/min
Now that we have the relative speed, we can find the time it takes for them to meet by using the formula:
Time = Distance / Speed
Distance between Ali and Tina = 1320 m
Relative speed = 110 m/min
Time = 1320 m / 110 m/min
Simplifying, we get:
Time = 12 minutes
Therefore, it would take 12 minutes for Ali and Tina to meet.
