The table shows the different times it takes Paula to drive to her grandmother’s house depending on the rate at which she drives. Rate vs. Time Rate (mph) 30 40 50 60 Time (h) 2 point 5 1 point 8 7 5 1 point 5 1 point 2 5 If one day Paula rides a scooter to her grandmother’s house at a constant rate of 24 miles per hour, how long should it take her?
The distance to her grandmother’s house is constant. At 30 mph for 2.5 hours, Paula travels 30 × 2.5 = 75 miles. At 24 mph, the time is 75 ÷ 24 = 3.125 hours, so the correct choice is A, 3.125 hours.
