Question

A truck driver drove 300 miles in 6 3/4 hours. How many miles per hour did the driver drive?

Answer 1

answer is 125 because you divide 300/6=50 

Answer 2

The truck drove 44.445 miles per hour.

Explanation:

Given:

Distance travelled driven by truck driver = 300 miles

Time taken =
`6(3)/(4)` hours.

To find:

miles per hour did the driver drive=?

Solution:

Now, we know that, number of miles per hour is nothing but the speed of the truck.

we know that, distance = speed x time.

So, now, 300 miles = speed x 6 ¾ hours

`300 = speed* ((6*4+3))/(4)`

`300 = speed*((24+3))/(4)`

`300 = speed*(27)/(4)`

`Speed = 300*(4)/(27)`

`Speed = 100*(4)/(9)`

`Speed = (400)/(9)`

Speed = 44.445
