11. Billy is running away from a Wells Fargo bank at a speed of 13 kilometers per hour (units are km/h). If the distance between the bank and the border to Mexico is 1.9 km, will he be able to get there before the cops arrive in 9 minutes? How long will it take for him to reach the border? (Hint: speed = distance / time, 1 hour = 60 minutes)
