Question 764412: It took Anne 8 minutes to walk around a square paddock. If she is walking at an average speed of 4.2km/h, find the width of the paddock in metres.
I have worked this problem out, but just want to double check.
My answer was 33.6m. I'm not sure if this is right though.

You can put this solution on YOUR website!
+8+ min is +8%2F60+=+2+%2F+15+ hrs
+d+=+r%2At+
+d+=+4.2%2A%28+2%2F15+%29+
+d+=+.56+ km
This represents 4 sides of a square, so
the width is:
+.56%2F4+=+.14+ km
+.14%2A1000+=+140+ m
the width is 140 m
hope I got it
