A car journey is in two stages. Stage 1 the car travels 84 miles. Stage 2 the car travels 35 miles at the same average speed as stage 1. Work out the time for stage 2, giving your answer in minutes

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
