Question

The snake slithered 2.25 m before resting on a rock. then the snake slithered twice as far as it did before, to catch a rat. when the snake headed home he slithered another 90 cm. what was the total distance the snake slithered?

Answer 1

2.25m + 2(2.25m) + 90 cm = 
2.25m + 4.50m + 90 cm
6.75m + 90 cm

1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m

6.75m + 0.9m = 7.65m <===

OR..

1m = 100 cm....so 7.65m = 7.65 * 100 = 765 cm <===
