Question

a new one-speed record has been set. This record was 129.562 miles per hour faster than the previous record of 633.457. What was the record-setting speed?

Answer 1

The record-setting speed is 763.019 miles per hour.

Explanation:

Given:

A new one-speed record has been set.

This record was 129.562 miles per hour faster than the previous record of

633.457.

Now, to find the record-setting speed.

Previous record = 633.457.

Faster by previous record = 129.562.

So, we add to get the record setting speed:

New record = Previous record + faster by previous record

`New\ record=633.457+129.562`

`New\ record = 763.019`

Therefore, the record-setting speed is 763.019 miles per hour.
