Question

Can someone help with this word problem?

We drove 450 miles at 70 miles an hour and it took us 5 hours to get there, if we drove 750 at the same rate how long would it take for us to get there?

Answer 1

that doesn't add up. It would've taken about 6.5 hours to travel 450 at 70 miles an hour

Answer 2

Thats the problem that was given? I did not understand it either

Answer 3

you sure it's not 350 miles

Answer 4

because that would be 5 hours

Answer 5

Positive. She wrote 450. If it was 350 could you show me the steps?

Answer 6

to solve this problem you divide the miles driven in this case 750 by 70 since you're traveling 70 miles per hour.

Answer 7

but 450/70 does not equal 5. 350/70 does or 450/90 does

Answer 8

Could you write it in an equation form please?

Answer 9

\[\frac{ 750miles }{ 70mph }\approx 10.7 hours\]

Answer 10

But notice that \[\frac{ 450miles }{ 70mph }\neq 5hours\]

Answer 11

that's why I wondered if you wrote it wrong. Or if your teacher wrote it wrong

Answer 12

Well it was an example that a classmates has to give for others to solve. Not sure if she messed up.

Answer 13

So it would take 10.7 hours to get there?

Answer 14

yes driving 70 miles per hour it would take approximately 10.7 hours to get wherever you were going
