60
Time (h)
2.5
1.875
1.5
1.25

If one day Paula rides a scooter to work at a constant rate of 24 miles per hour, how long should it take her?
2.625 hours
2.75 hours
3.125 hours
3.75 hours

Respuesta :

speed = distance / time
30 = d / 2.5
30 * 2.5 = d
75 = d

40 = d / 1.875
40 * 1.875 = d
75 = d

50 = d / 1.5
50 * 1.5 = d
75 = d

60 = d / 1.25
60 * 1.25 = d
75 = d

24 = 75 / time
time = 75/24
time = 3.125 hours

Answer:

75 miles / 24 mph = 3.125 hours
