Question

A scientist finds the fossil of a dinosaur foot print which is 33cm 8mm long.another dinosaur footprint is 5mm longer than what is the length?

Answer 1

The length of another dinosaur’s footprint is  34 cm 3 mm.

Step-by-step explanation:

Required conversion:

• 1 mm = $\frac{1}{10}$ cm

The length of the footprint of the  first dinosaur found by the scientist = 33 cm 8 mm

The length of another dinosaur's footprint is given to be 5 mm longer than the first one

Using the conversion we have:

33 cm 8 mm = [33 + 0.8] cm = 33.8 cm

5 mm = 0.5 cm

Thus,

The length of another dinosaur will be,

= 33.8 cm + 0.5 cm

= 34.3 cm

= 34 cm 3 mm
