Bill spends two days driving from Point A to Point B . On the first day, he drove 2 hours longer and at an average speed 5 miles
Rainbow [258]

Answer:

His average speed on the second day is 35 miles per hour.

Step-by-step explanation:

Consider the provided information.

On first day, he drove 2 hours longer than he drove on second day.

Let x = Number of hours he drove on second day.

Then x + 2 = Number of hours he drove on first day.

It is given that he drove a total of 18 hours.

Therefore,

x + (x + 2) = 18

2x + 2= 18

x=8

He drove 8 hours on second day.

x + 2 = 8+2=10

He drove 10 hours on first day.

Let y = speed driven on second day.

y + 5 = speed driven on first day.

As we know: Distance = speed × time

On first day he covers a distance of:

Distance = 10(y+5)

On second day he covers a distance of:

Distance = 8(y)

Total distance = Day 1 distance + Day 2 distance

10(y+5) + 8(y) = 680\\10y+50+8y=680\\18y=630\\y=35

Hence, his average speed on the second day is 35 miles per hour.
