Leo Sam
After 1 minute: 65 105
After 2 minutes: 130 210
After 3 minutes: 195 315
Now there is a difference from 100 meters

Answer:

Sam will catch up his brother in 2.5 minutes

Step-by-step explanation:

Two equations can be written to represent the problem.

Sam: y1 = 105*t

Leo: y2 = 100 + 65*t

where y represent position, in meters, and t is time in minutes. That is, after 1 minute after Sam started to run, Sam will be at 105 meters of distance from the house, and Leo will be at 165 meters of distance from the house.

When Sam catch up Leo, the distance travelled by both equals:

y1 = y2

105*t = 100 + 65*t

105*t - 65*t = 100

40*t = 100

t = 100/40

t = 2.5 minutes
