Question

Tom's drive to work is 71/5 hours, whereas Robert's is 11 hours. How much longer is Tom's drive than Robert's?
Simplify your answer and write it as a fraction or as a whole or mixed number.
16/5 hours
17/5 hours
15/5 hours
14/5 hours

Answer 1

To find out how much longer Tom's drive is than Robert's, we need to subtract Robert's driving time from Tom's driving time.

Tom's driving time: \( \frac{71}{5} \) hours
Robert's driving time: \( 11 \) hours, which can be converted to a fraction:
\( 11 = \frac{11 \times 5}{5} = \frac{55}{5} \) hours

Now, we can subtract Robert's time from Tom's time:
\[
\frac{71}{5} - \frac{55}{5} = \frac{71 - 55}{5} = \frac{16}{5}
\]

Thus, Tom's drive is \( \frac{16}{5} \) hours longer than Robert's drive.

The answer is \(\frac{16}{5}\) hours.
