Maths Question

[saintpeter48]

A car travelling at 30 MPH will take how long to travel 33 miles? This was on The Chase recently and I just can't get my head round it, any help please.

distance/speed = time

33/30 = time taken

[Etch]

Time taken (in hours) = distance (in miles) divided by speed (in mph)
So 33/30 = 1.1 hours
Multiply by 60 to get answer in minutes
1.1 x 60 = 66 minutes

[Old_Geezer]

It'd take an hour to do the first 30 miles.

It'd take a tenth of an hour to do the additional tenth of 30 miles. A tenth of an hour is 6 minutes.

60 minutes + 6 minutes = 66 minutes.

The way I do it is to think 60 mph is a minute a mile....so 33miles is 33 mins.
But this in only going at 30mph, that's half of 60mph so takes twice aslong...so 66 minutes as the others all said

[gingejbee]

Isn't it just simple mental arithmetic...33 miles is 30 miles plus a tenth, so it'll take an hour and a tenth ie 60 plus 6 minutes.

[bobbinwales]

Seems that way gingerbee but not everyone sees things like this....am wondering what Saintpetr thought it was or why 66 mind seemed odd

[saintpeter48]

My first thought was 33 minutes, it took me ages to work it out, maths is not my strong point, thanks everyone.

I think there is a set of people whose brains freeze when they think they have to do maths. I feel certain that, had the distance been 60 miles, StPeter would have had no difficulty giving the time; it's just that his brain told him that maths was involved and it froze.

66 mins as above did the contestant get it right?

[Barsel]

Fascinating how many different ways there are of working it out.
If I was asked that question I would just say an hour and a bit!

[elliemay1]

I would do it the hour and a tenth way

[bobbinwales]

30 miles in 60 minutes means 2 minutes for each mile....so 33 miles takes 33 z 2 = 66 mins.
All these aspersions of how to work it out look very similar to me...just break it down into steps....think about what 30 miles per hour means...treat it as a real life problem don't think ofit as maths because for some people just go into a panic thinking of school maths or li

[Barsel]

elliemay, that sounds good, but I'm not sure my brain is quick enough these days to do that. Certainly sounds the simplest way to me.
