Answer:

  about 7.61%

Step-by-step explanation:

Put the given numbers into the formula and solve for r.

  2200 = 1900(1 +r)^2

  √(22/19) = 1 +r

  r = √(22/19) -1 ≈ 0.076055 ≈ 7.61%

Chloe drives from her house to her Grandma's house 48 miles away in an hour and 12 minutes. How fast was she driving on average?
Lera25 [3.4K]

To find a speed in miles per hour, we need to divide a number of miles by a number of hours.

We are given 48 miles, so we already have a number of miles.

We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.

1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours

speed = distance/time = 48 miles / 1.2 hours = 40 mph

Answer: The fourth choice, 40 mph.
