Question

The Raimonde family drove 1,764 miles across the United States on their vacation. If it took a total of 28 hours, write and solve a multiplication equation to find their average speed in miles per hour.

Answer 1

Multiplication equation is
`Distance= Speed* Time` →
`1764= Speed* 28`.

Speed is 63 miles per hour.

Explanation:

We are given that,

Distance traveled by Raimonde family = 1,764 miles

Time taken by the family = 28 hours.

It is required to find the speed in miles per hour of the family.

As, we know,

`Speed=(Distance)/(Time)`

i.e.
`Distance= Speed* Time`

So, we get,

`1764= Speed* 28`

i.e.
`Speed=(1764)/(28)`

i.e. Speed = 63 miles per hour.

Hence, the average speed of the Raimonde family is 63 miles per hour.

Answer 2

The answer is 63 miles per hour.

The distance (d) is multiplication of speed x and time (t):
d = x * t

d = 1,764 mi
t = 28 h
x = ?
1,764 mi = x * 28 h
x = 1,764 mi / 28 h
x = 63 miles per hour
