The answer is ten hope this helps :-)
Let's say the first number is "a"
the next consecutive can just be "a+1" and the next, you guessed it, "a+2"
the two smaller ones are a and a+1, the larger one is a+2
now, the product of "a" and "a+1" equals 5 times "a+2" but less by 5
thus a(a + 1) = 5(a + 2) - 5 <----- solve for "a"
Distance traveled during the first 4 hours: 500 m Note that the rate here was 125 m/hr.
Distance traveled during the next four hours: 3(125 m/hr)(4 hr) = 375 m
Total distance traveled: 500 m + 375 m = 875 m
