Chris and goffy ran from newton to boston at 15 km/h and 12 km/h respectively. they both started from newton at 10: 00 a. m. if goffy reached boston at 10: 30 a. m., at what time did chris reach boston ?

The Answer is 10:24 am because...

Chris=15km per hour

Goffy=12km per hour

So Goffy took 30 minutes Boston=6km from Newton. So Chris took 24 minutes and he got to Boston at 10:24 am

Hope this Helps you!      :)

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
