Jacob travelled 708 km on a bus in 8 hours. Alissa travelled 496 km on a train in 5 hours. What was the speed per hour of the faster vehicle?*
99.2 km/h
62.0 km/h
141.6 km/h
88.5 km/h

99.2

Step-by-step explanation:

Speed = distance÷time

496÷5=99.2

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
