Answer this question:Jack bought an ice cream cone before jogging to the beach. If the ice cream cone will melt in 10 minutes, the beach is 16 blocks away, and each block is 1/8th of a mile, how fast does Jack need to jog (in miles per hour) to get to the beach before the ice cream melts?
First find the total distance to the beach: 16 blocks * 1 / 8 mile / block = 2 miles. Then find how long in hours Jack has to get to the beach: 10 minutes / 60 minutes / hour = 1 / 6 hour. Then divide the distance Jack needs to cover by the time in hours he has to find how fast he needs to jog: 2 miles / 1 / 6 hour = 12 miles / hour.
The answer is 12.

Answer this question:The sum of Mario and Maria's ages now is 7. Mario is 1 year older than Maria. How old is Mario?
If x is Maria's age, then Mario's age is x + 1. The equation that represents the sum of their ages is x + x + 1 = 7. By combining like terms, the equation becomes 2x = 6. Hence, the value of x which represents the age of Maria is 6 / 2 = 3. So Mariu is 3 + 1 = 4 years old.
The answer is 4.

Answer this question:Every day, Lou works out by running three miles on a circular track that is one-quarter of a mile long. His wife, Rosie, also runs on the same track at the same time as her husband, but she runs at twice the speed of her husband. During their workout, how many times does Rosie circle the track?
If Lou runs 3 miles during his workout on a track that is 1 / 4 miles long, then he circles the track 3 / (1 / 4) = 12 times. If Rosie runs twice as fast as Lou, then over the same time period, she runs 3 * 2 = 6 miles. If Rosie runs 6 miles on the 1 / 4 mile track, then she circles the track 6 / (1 / 4) = 24 times.
The answer is 24.

Answer this question:Chad has 100 apples and each apple has different sizes and different price ranges. Each small apple cost $1.5, medium apple cost $2, and big apples cost $3. If Donny bought 6 small and medium apples and also 8 big apples, how much will Donny have to pay for all of it?
Donny was charged $1.5 x 6 = $9 for the small apples. He was charged $2 x 6 = $12 for the medium apples. And he was also charged $8 x 3 = $24 for the big apples. Therefore, Donny has to pay $9 + $12 + $24 = $45 for all the apples.
The answer is 45.
