Maria drives at a rate of 60 miles per hour. It takes her 3 hours to get to her aunt's house. How long will it take if she drives at a rate of 50 miles per hour?

3.4 miles

Step-by-step explanation:

60 × 3 = 180

she has to drive 180 miles

180 ÷ 50 = 3.4

3.4 miles

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
